Helloooo new Punter. I don't have a database that I can run your systems through but I'd imagine that the loss on each would be around 15% because you're using pretty standard filters.

I'll have a stab and say the last start winner system would be close to a 20% loss, the 30% system just over 10% loss and the first upper about 10% loss too. The track and distance scenario's reduce your profit.

I've just spent the last month or so reading almost every post on here ..... enlightning it was ! It's worth doing !

Good luck, I hope someone comes forward and runs your systems for you.
