What happening if last 5 roll not smaller than 66 and if last 5 roll not smaller than 66 ? Chance = 33 or chance = 49.5 ?

It made me confused. MMM... It can be like this ;

if last 5 roll smaller than 49,5 ,

nextbet is 1, and chance is 49,5

else 0.001 and chance is 49,5 (payout 2x) ----- Odds of losing 5 bets in a row at 49.5000%: Once every 30.45 bets.

if last 8 roll smaller than 66.99

nextbet is 1, and chance is 33

else nextbet is 0.001 and chance is 33 (payout 3x) ----- Odds of losing 8 bets in a row at 33.0000%: Once every 24.63 bets.

if last 11 roll smaller than 75.24

nextbet is 1, and chance is 24.75

else nextbet is 0.001 and chance is 33 (payout 4x) --Odds of losing 11 bets in a row at 24.7500%: Once every 22.83 bets.

if last 8 , 9, 10 roll smaller then 49,5 chance is 49.5

if last 11,12,,13,14... roll smaller then 66,99 chance is 66.99

BTW thank u so much
