HANDLING EXPECTED RUNS OF OUTS

Using mathematics we can predict fairly accurately the expected maximum losing bets in a row using the base strike rate for our method.

The Formula for calculating expected Losing Sequences is:
1 divided by (Losing Strike Rate divided by 100) to the power of 'number of run of outs'.
(Note: Losing Strike Rate is 100 minus the Win Strike Rate).
Example for a Strike Rate of 28% to see how often I should experience a sequence of 14 losers in a row:
=1/(78/100)^14
=1/.78^14
=99.35
=99 (rounded)
Conclusion is every 99 Bets I may expect to see 14 losers in a row.

A Bank Size should be set to absorb this runs of outs with ease during 100 bets.
Which means for Win Betting I allow for 14 losses in a row an for Ratings Staker I allow for 6 losses in a row.
Personally I set my Bank to this figure to absorb a run of double this amount with to avoid the bank going bust and minimize any times I have to top up my Wagering Accounts.

Whilst the below Table Example may be frightening in ways, you should use them as a reference for not panicking when experiencing an expected run of losses in a row. Also if you are experiencing more runs of outs than expected it is a signal that your Win Strike Rate is likely altered and your methods should perhaps be reassessed.
