in the least, the btp is "fully optimised." so at least in one way (of "every way"), your statement isn't true. also, i distinctly remember frame advancing to the exact frame you can press start to begin the match before every match. can't imagine further optimising that.
it's just bad style for a taser to improve a previous run and then throw around words like "fully optimised." firstly, you have that run to beat-- so of course the second taser will have to optimise it further. someone can just as easily go in after the second run and fine tune it here and there. it's like that for plenty of tas's-- a few seconds here, couple there.
