Some Questions

[etherial]

I haven't done this degree of in-depth analysis for the ED4 version of the system, but in general, the more dice you have, and the larger the dice, the more the bubbles and hiccups of the individual dice cancel or balance each other out. And, aside from a few places at the margins where the difference is marginal at best, you are always better off increasing your Step.

The other significant bump in the road is at Step 19, where the d20 is added. The Variance increases by almost 50%, so while the Expected Value is 19 as it should be, the dice are much more likely to fail spectacularly (and succeed spectacularly). It can be really hard to go from very consistently rolling in the 16-20 range with Step 18 to being all over the place with Step 19.

I thought I used anydice properly.

Did I mistype something?
Maybe.

[Lursi]

Ah, I see where I screwed up...
Correct is:
output 5d[explode d4]
Every four is rerolled
I failed with
output [explode 5d4]
Only when all dice show a four there is a retoll.

...where the d20 is added. The Variance increases by almost 50%...

This is intentional, and IMO has been since the original version of the system.
