Has he already reached the limit of the speed enhanchment from nen? Like, does he need the pirate system to go further or could he improve with just nen and the force? As far as i understand the problem is his body not being able to endure the boost to his muscles, but can that be improved by learning to enhance better? He was at level 2 (to break 1000 boulders with 1 rock) last time. Maybe if he reaches level 3 he can go faster? If the technique is better the strain on the body might be lowered. Or he can enhance his body's durability to resist the strain.
Ooooo, this is(i think) a good question. What does the tavern expect from ray? Like are they expecting him to possibly fall like Anakin did, go insane, or hunt down players that's gone insane or somwthing? I like the idea of him being some wildcard they have a hard time predicting what he'll do cause he seems to genuinely be in balance.
