Conditional probability chart for EV of remaining shoe

Does anyone have a good reference for this?

Input would be:
* Counting system
* Rules
* Cards remaining
* Running count
* Bet spread

Output would be...Expected ROI% on remaining shoe (b4 shuffle).

Example:
* Hi/Lo count
* 4dk game, S17, DAS
* 150 cards remaining
* Count: Disadvantage 6
* Bet spread = 10:1

Output = ROI ???

Surely it's negative, b/c you don't you don't figure to see many +EV hands. Would be nice to when it's the appropriate time to depart the table.

Bravo to anyone who has something similar to this!
