A mathematician
has done some work on these losing runs, based on the average %
of winning bets usually made.
Note: these
are not set in concrete but are a reasonable guide as to what you
may expect to happen from time to time.

Obviously, you will hit these average
and worst case scenario losing runs now and again. How often will
it happen? Don't know. Nobody does.
It's why it's called gambling. However you select your winners,
work out your average hit rate and change your staking plan according
to what you
may expect to happen in order to limit the damage.
