Thanks for the replies guys. I've got lots of stuff here ranging from getting a mathematics degree to sticking to level stakes and even giving up completely as I have lost 40%. (The above is meant with tongue in cheek but I can't find the emoticon for it).

I will take them all on board and have a think about it. In the meantime I will lower my liability stakes but continue to use percentage staking without the ratcheting.
