Ok, so to spell this out. With the recent (I assume) update to the bios that have added the first appearances of the Vengeance heroes, we now know Parse's first appearance was in Mystery Comcis #97, just 70 issues after Maia Montgomery made her debut.
We also know that Omnitron and Cosmic Omknitron debut in the same issue of Freedomf Five (#305). Which is an interesting fact in and of itself. The original Omnitron appears to have been a one issue fight for the Freedom Five. A throwaway villain who was resurrected later when it proved propular.
Given that Parse's bio states she gained her abilities from the event that created Cosmisc Omnitron, Mystery Comics #97 must occur after Freedom Five #305. But that means Freedom Five had 300(!!) issues while Mystery only had 70. This is, just about, possible if Freedom Five was a weekly while Mystery was a monthly or similar schedule but dang, that's a big gap to fill in.
I suppose it's possible that Kim Howell appears in Mystery Comics #97 as an unpowered investigator (Mystery Comics #98 appears on the text of Snap Decision, incidentally), rather than as Parse. Or that Mystery comics is a series that's cancelled and restarted multiple times but that's a bit of a cheat to people trying to put the timelines into some kind of sense.
So, how on Earth can these timings be reconciled?
