Looks like Endless Zone isn't as unpredictable as we thought it was.

The formula f(x,y) = 1 + (y - 1)*(0.3 + 0.05x) gives the total strength of wave y in level x. For example, the fifth wave of zombies in level 34 is a total of nine "strength". Zombies are worth one strength; coneheads, two; bucketheads, four. A lot of world-specific zombies also have easily determined strength numbers. So fifth wave, level 34 can have two bucketheads & a zombie; or two coneheads, a zombie and a buckethead; or nine regular zombies. It's not much, but I think it's kinda cool that you can track how strong a zombie is compared to others. If anyone wants, I can post a list of zombie strengths I've compiled so far.
