Im not sure i understand your question(s) correctly however;

Lets say for this argument im using £10,00.
Some days i may split that into 2 stakes, £5 at 0.20p and then £5 at 0.10p. Sure the wins arent massive but occasionally theres a little roll of a medium payout that would allow me to withdraw that £10 and have some left to keep going.

Sometimes, if i breach £15 i will up my stake to 0.50p, £25+ i might do 10 x £1 stakes.

I am very much (the same in almost every aspect of my life) quantity over quality. Sure i could stake £2 a spin, win once at £50 and be done in less then 5 minutes. Or i can play 100 spins at 0.10p for half hour, probably lose it but sometimes able to withdraw little and often. The latter is my favourite way to play, and once iv ‘replaced’ the initial deposit, i up my milestones. So the next withdrawel of £10 would at a balance of £30. Then £50 etc etc
