Im almost mad at myself for continuing this conversation lol.
Tipping pucks is a developed skill that is practiced OVER and OVER again by players. It's engrained as a mechanical process the body deems second nature. That's why we hear about players doing tip and deflection drills. You could easily estimate a player tips over a thousand pucks a year in practice or game scenarios. Also, in almost every tip situation, the player deflecting is 100% focused on the puck, and is stationary (or relatively stationary). Determining angle and the physics of one moving object is much easier than two (Perry skating towards one direction and Tavares falling the other way).
While you are correct that plays are made on peripheral vision, you cannot align the way players are looking for oncoming checks or passes to Perry actively looking for a player tumbling towards his legs while the puck is 25 feet up the ice. The former situations are expected events and engrained into a players movements. The latter is ad hoc.
You are arguing two things, and I dont think either is valid. This is an abnormal play, and you shouldn't be taking normal actions a player may do (tipping pucks (which still takes more than .3 seconds from my rough timing I just did)) and trying to use them to justify (or unjustify) Perry's actions for an ABNORMAL situation. No player builds in the muscle memory to avoid tumbling players coming towards them. Do they work on high steps or general avoidance? Of course. But this specific situation is not practiced like tip drills.
If you think Perry has the time to CHOOSE the better of and infinite list of potential actions in a super finite amount of time, you are giving the human body and brain wayyyy too much credit. Perry tried to jump over because that's instinctively what a person would do when something is falling at their feet. Their body ISN'T thinking - its reacting. Planning to do something else isn't logical. Perry reacts, but circumstances didnt allow for a better outcome from the proper natural reaction.
