Crimson Balrog schedule?

None of those matters when we're talking about milliseconds.

Well I guess I didn't understand the post. I thought he meant something like:

If (milliseconds < 600) then 60%scroll_pass else 60%scroll_fail

Someone with stable internet could easily abuse that.

If however, the millisecond count is used as the entry into some semi-randomized lookup table, then that could be as good as actually using a random number generator function, and a lot quicker.
