Delay? WaitTimer? WaitEvent? Delta timing?

Okay, that was helpful, but still I have a couple questions. First, what was the deal with WaitEvent -- why did it cause such uneven slowing? Second, what do you mean by "every addition equation" in your delta timing example? Third, I'm looking at the "Product updates" page -- you mean "BlitzPlus Update V145," not "BlitzPlus Version 1.11," right, since I have the main thing already? (And it is V145, not V140, isn't it?)

Also, as I said, I have seen a little slowing down when I've been using Delay and a lot of enemies show up all at once, but I don't mind it much because it's so constant, which WaitEvent sure wasn't.

Thank you for your help so far, and please keep on going!
