Sorry but that's simply wrong. I have done two years or sabre fencing in my youth - it's all about reaction time and correct execution of a parry. If you always knew exactly which angle to parry at, and had the reaction speed to execute this in time, then you could fence for a long time without anyone getting hit. You'd have to outsmart your opponent by slowly leading them into a trap where they have to execute a movement that throws them off-balance, so that you then can execute an attack that they can't regain their balance to parry.

The issue is lunges are slower and cover more distance allowing another force sensitive opponent ample time to react

Imagine play fighting in slow motion. You can do it pretty much forever without getting hit by blocking or dodging everything. Unless you get tired or your body cannot physically react to something
