I'll keep this updated as I level up. If anyone else has F2P experience data to contribute please do or start keeping some. Would be nice to figure out if its a set cap that gets lower or if its a number that is subtracted from your max pulse. I am hoping to see it reach a limit at some certain level but this may not be the case.
