That's why I've taken the bulk of it out UB, I'm not confident in my methods I think its simply been a lucky/good run picking quaddies with no method but reasonable confidence in my selections.

If I were actually betting a system I had full confidence in long term then it definitely makes sense to keep the betting bank available as then you can bet a % of your bank and compound over the long term. What i'd actually do in my situation is have most of my betting bank offset my home loan and therefore its saving me 4.5% interest plus its readily available if needed for betting and you can compound it into here as well.
