There has been a ruling on this before - I recall it coming up oodles of times, and Gordon stepping in - but I can't find it. So.....
Due to evidence presented for and against in the past, Movie Star Wars characters are not bullet-timers.

Come vote on the league match of the century.
Peter fought off the whammy, and once he did, he's basically been immune in the two or three times they have tangled since. It's still a very useful skill in a Rumble against anyone else, though, since Peter took a LONG time to shake it, and, in the Arena, Lizzie's not going to need too long against someone who hasn't developed the immunity.
Lizzie should win against Peter in HtH, but once you throw in light sabers, Pete's danger sense, much greater skill and at least equal speed would seem likely to gain him the advantage. Peter never has much trouble hitting Connors, he just can't do much damage to someone stronger and so much more durable. Give him a reach-extender that can cut through Lizard like paper and he probably takes the fight all by his lonesome. I don't see Lizard's current form being nearly as handy with a saber, NOT counting the spider sense telling Pete how not to hurt himself with a massless-and-cuts-through-damn-near-anything-blade.
If you are questioning whether Pete's reflexes will work like this, remember, the reason that Pete never gets caught changing is because his spider sense prevents him from changing where he'd get caught. His webs never hook onto something that'll break under his weight because the spider sense guides his shots. This was recently expressly shown and narrated as such when the sense was stripped from him - he kept falling out of the sky when he'd web something or swing off something that wouldn't hold his weight. And the "don't get caught changing" thing has been documented repeatedly.
