OK, thank you.

Okay. What did you think about this:

>>
>> ⒈ local tmp1 = DRIP()
>> ⒉ local tmp2 = DRIP()
>> ⒊ local tmp3 = DRIP()
>> ⒋ WHIP(2*N + tmp1)

>> ⒎ CRUSH()
>> ⒏ WHIP(2*N + tmp2)
>> ⒐ tmp3 += DRIP()
>> ⒑ CRUSH()
>> ⒒ WHIP(2*N + tmp3)
>> ⒓ a = 0

I think (intuition, not science; I’ve written down the idea
basically as soon as I had it) that it should reduce loss
of entropy in the state, which would benefit use of Spritz
as RNG, and not harm use of it as hash and stream cipher
other than a slight speed reduction.
