It sounds as though you were spotting over priced horses in the morning backing them to win? But a fair few times they were coming in before the event? (if so thats gold for Betfair, you could back them on the exchange and then trade out before the event by laying it).
I noted as well you asked about covering the subs, I'd aim to try and see the subs and the community as an investment in your education of trading first.
