game question

1 deck, 7/8ths dealt
DOA, no DAS, split only once for a total of 2 hands

play only 1 spot, use high low with all multi deck EV indices -2 to 10, leave game at TC -2

bet:

<= 0 TC $10

1 TC $100

2 TC $200

3 TC $300

4 TC $400
>= 5 TC $500

Would appreciate it if anyone can tell me the % advantage and average bet. Thanks
