Well, i thought the whole point of this was for it to be the same as betting, just without using money - so risk free, just fun...

If that is the case then i would leave it like it is - but maybe consider reducing the initial 10k to maybe something like 3k.... to easy to put 5k on a 2-1 fight and get lucky and get a good lead going.. 3k will take some good thinking, some luck to finish top.. not that me about to finish top wasn't luck either
