youre going in the right direction, but whatever you are doing isnt very efficient. you are definitely missing some SP in your build. my CB should have a slightly better build than that at level 6.
i see you are making a returner, so here is what i would do:
speed to 83 cap
agility to 77 cap
carrying to 68 cap
strength to 68 cap
vision to 60 cap
after you can speed at 48 (youve done this already), you should start training agility. once you get speed to the 83 cap with SPs, continue to train agility until you can cap it. once you have capped agility at 48, start training carrying... ect, ect.
