the worst,??

Probabally the worst thing was to spend months testing a selection process that worked.

Then, starting with a bank, betting following the tested selection process.

Then when the bank doubled, i thought how good is this !

When the bank trippled, i thought, how EASY is this,

(i was backing the runners win 1x4 place)

so, i looked at how often i was getting the winner, 44 %"ahh, i can just put it all on for a win, im too good at picking the winner, i dont need the place component"

Well, i didnt take into consideration that the place percentage was "backing up" the loosers, so when i doubled my outlay (because my bank doubled)
the run of normal outs ate my bank away and i looked and thought how did that happen.

So, i will build a bigger bank and not get GREEDY.
Next time, i will wait for my bank to be 5 x original before betting higher, stay with what i know in selections, and walk away when the bad day starts
