So now that I finally feel like I understand how the Jokearo Customization Works, I did some work calculating to probability of getting certain results with different sized units of Jokearo.

First off, to make things simple, here are the acronyms I will be using for that Table

1- NA (the nothing roll, also if you roll 2 6+'s after getting a second roll on the table)

2- +R (Only extra Range)

3- +Sv (Only better Save)

4- Rend (Only gain rending)

5- 5++ (Only gain INV save)

6- 2x (This is the chance of getting two Different upgrades after getting a second roll on the table. I did not separate all of the combinations)

---------------------------------------
Unit of 1 Jokearo

NA- 18.5%
+R- 19%
+Sv- 19%
Rend- 19%
5++- 19%
2x- 5.5%

---------------------------------------
Unit of 2 Jokearo

NA- 3.7%
+R- 21.3%
+Sv- 21.3%
Rend- 21.3%
5++- 21.3%
2x- 11.1%

---------------------------------------
Unit of 3 Jokearo

NA- 12.5%
+R- 0%
+Sv- 26.4%
Rend- 26.4%
5++- 26.4%
2x- 8.3%

---------------------------------------
Unit of 4 Jokearo

NA- 29.6%
+R- 0%
+Sv- 0%
Rend- 33.3%
5++- 33.3%
2x- 3.7%

---------------------------------------
Unit of 5 Jokearo

NA- 57.9%
+R- 0%
+Sv- 0%
Rend- 0%
5++- 42.1%
2x- 0%

---------------------------------------
Unit of 6+ Jokearo

NA- 100%
+R- 0%
+Sv- 0%
Rend- 0%
5++- 0%
2x- 0%

Conclusions

1) Having a unit of 2 gives you the Least chance of getting Nothing.

2) Having a unit of 2 gives you the Most chance of getting 2 upgrades.

3) A unit of 3 gives you less chance of getting nothing than a unit of 1.

4) A unit of 4 or more gives you a Greater Chance of getting Nothing than a unit of 1.


It would seem that a unit of 2 is the best option for a unit of Jokearo in order to Maximize their use of Customization, as you have the greatest chance of getting 2 upgrades, the least chance of getting nothing, and you are still able to get all of the possible upgrades as well.

3 Jokearo seems to be an Okay choice as you still have less of a chance of getting nothing that only 1 Jokearo.

For units with 4 or more Jokero, they should expect to be used only for their weapons and not their customization as they increase the chance of getting nothing from the unit.

i think you roll for each jokero separately, the effects just dont stack.

Wow really, have you even seen the entry before you answered.

2 Jokaero are optimal for Inconceivable Customization. Unfortunately, the rule is not particularly good, since it works best with anti-infantry/torrent of fire units, and Codex: Grey Knights already has an ample supply of such and really doesn't need more.

Thank you for doing this math. I disagree that units of 4 Jokaero should be used simply for their weapons. A unit of 4 Jokaero is actually the best way to get the rending rule, if you are specifically going for it. It really depends on how you want to build your unit, for example:

4 Jokaero
8 Acolytes with Storm Bolters

This unit would have a 2/3 chance of getting either rending or 5++ saves, and a small chance to get both. Both are wonderful upgrades for the Acolytes.

I was thinking about taking 4 and going for the rending, BUT I really do not think it is worth it.

You pay 70 pts for 2 and 140 for 4. Even with this you only have about a 10% greater chance to get rending. Remember that part of the chance of getting two is getting the rending option. I would rather pay half as much and almost always get something rather than paying double and having a decent chance of not getting anything.

Think of it this way
1 unit of 4 Jokearo and 8 storm bolters = 196 pts

2 units of 2 Jokearo and 4 Storm Bolters = 196 pts

by splitting them into two units, both units will probably get some bonus on the table, and there is a much greater chance that some of your storm bolters will gain rending. If you have the FOC slots, this is the way to go.



My jokearo unit will look like this

2 Jokearo
3 Melta Gun Warriors
5 Storm Bolter Warriors
Clocks in a 147 pts total. They will be mounted in a chimera


Honestly, it is a little higher than I would like, but it is okay. You have stuff that would benefit from any of the rolls on the table.
Extra Range? Good on the melta guns and multi-meltas. Super long range Lascannons.
Armor? not my favorite, but you get saves against bolters and the like now.
Rending? 5 Storm bolters and 2 heavy flamers.
5++? again not the best, but decent.


If you think that 35 pts is a good price for a BS3 lascannon. multimelta, or Heavy Flamer, then by all means take more of them, but you start to loose out on the bonuses on the customization table.

Your math is all Kinds of Wrong(or your presentation of it is).
For a unit with 1 Jokero; all outcomes are equal: 16.667% chance, as you increase in Jokero you decrease the lower numbered results by that same 16.667% and increase tohe duplicate result by the same amount.

If you wanted to run the numbers based on Adding a further chance to each result for the 2X rolls result then you increase each Item by 5.556% to represent that there is an added 16.667% chance for the additional rolls, assuming that the first roll was a 6. The only options that would still see any true increase is the Nothing result(based on doubles) and the 2x result.

For a unit with 1 Jokaero, lets us take getting the result of ONLY having extra Range.

The first roll give you a 16.667 percent chance for rending (you roll a 2). 1 out of 6 times you will get two more rolls on the table.
On those 2 other rolls there is a 5/36 chance to ONLY get extra Range (rolls of 2+1 2+2, 2+6 1+2 6+2)

Result: 1/6+(1/6*5/36) = 16.667%+2.31% = 18.98% which I then rounded to 19%

This can be repeated for any other single result

========

To get Nothing
First roll is a 1/6, If you get a second roll, there are 4/36 results that give you nothing (1+1 1+6 6+6 6+1)

Result: 1/6+(1/6*4/36) = 16.667% + 1.85% = 18.51%

=========
To get Two Different Results ( not rolling a 6 on the chart, but ending up with two upgrades ie, Rending AND Extra Range)
First you must roll a 6, Then you have a 12/36 chance to roll two different results (2+3 2+4 2+5, 3+2 3+4 3+5, 4+2 4+3 4+5, 5+2 5+3 5+4)

Result: 1/6*12/36 = 5.55%

=============
=============

That is the process I went through. It was probably not explained well at the top of the thread. The 2x means that you end up with two upgrades, not that you got the "Roll again with two dice" result on the first roll.

There is always the Chance that I made a mistake somewhere, but I think that my basic method was sound.


Edit: I changed the explanations on the first post a bit. I think it was a little confusing at first.

Ok, that is why I had put the Parentheticals in my post: the presentation was confusing. The math still checks out of course(which I had verified in my post and was the reason for my parenthetical).
