• Category annotations are removed
• Added check for the case when petal has very small positive velocity

It makes more sense to me in hindsight after reading this. What confused me is that what you call an "analyzer" is in effect a database of excitation levels. It's not even implied that it performs any kind of filtering or transormation to those readings, it just stores them. As you said it's not a big deal regarding the kata itself, I was perhaps reading it too carefully, thinking it was relevant to the task.

Okay, In this case, I will just remove Category annotations.

Not a problem.

Ok, O'Brien

If I understand correctly the current RNG relies on the fact that there is no number below 98 ** 8 that has both an integer 8th root and an integer 7th root, except 0 and 1. (the first that I could find is 72057594037927936 == 256 ** 7 == 128 ** 8, which still fits in a signed 64-bit but is excluded by the current range). It seems to at least deserve a comment to explain that.

I don't like that the negative cases are numbers of a special form (they have an integer 7th root by construction) but I think it is good enough. I reckon hobovsky meant a bare rand() call for those, though in that case you need a reference solution on the off chance that rand() generates a positive case.

hi, made changes

Hey @hobovsky 👋
Just wanted to check in and ask how long the "Awaiting approval" phase usually takes/lasts?

I updated the description. What do you think?

Hm, I thought that this would be obvious enough to allow not specifying it explicitly, but now that I think of it, it seems that it should be specified.

Will do a bit later.

Noting that OCaml has for completeness

Haskell now has.

LC now has.
