This works a treat when the right winners come along because punting has hot & cold runs.

1/200th Staking Plan
Bet 0.5% of your current bank. (1/200th)
After every 5th bet, adjust your bet to 0.5% of your current remaining bank.

That means the bet stays the same for 5 bets.
Then Bet 1/200th (0.5%) of remaining
balance , up or down.
