Your strategy works... until it doesn't. You are still in the pleasant before phase. You will not enjoy the after phase.
So let's take you at your word and say you've increased your BR by a multiple of 82. We can choose any number but let's assume your starting BR is $100. Your BR now is approximately $8,200.
You supposedly have 96% of your BR affected by the outcome of one fighter (Mike Pierce) and this is a repetitive strategy you employ (apparently you've done similar things with absolute locks like GGG). When that absolute lock eventually loses - and they always do - even if your read is PERFECT (i.e. fighter injury like Jon Jones' toe had it gone to R2, atrocious reffing, atrocious judges' decision, etc.) you sir are penetrated.
Your BR will go from $8,200 down to $328. Yeah, your multiple will no longer be 82 but instead around 3 thanks to the variance of one outcome.
This is categorically the DUMBEST betting strategy possible. Even a monkey throwing 10 darts on random bets has less risk of ruin than this strategy...
...Actually, that's not entirely true. The dumbest strategy is betting 100% of your BR. At least you've left yourself with enough money to buy a pistol and put yourself out of your misery.
