A minor nitpick on the copy (and even then, it might just be me): I find "97% speedup" and "50% speedup" really hard to parse — a "30x speedup" or "97% reduction of time taken" immediately tell me what is being achieved!
Great results once I get my head around them, though!
That's why it's confusing: "2x speedup" would clearly indicate 200% of the current speed, so 97% speedup is unclear if it's a multiple (not because that would be a slow down), a reduction in time (which was my assumption) or an increase in speed (something per unit of time).
I guess you are right and it's probably the latter, but obviously better language would have avoided any doubt.
