Ran a sim playing Hi/Lo with 60 indices, heads up, 65% pen, no preferential shuffles, H17, DOA and a 1-to-30 spread ($25-to-$750) never more than tripling nor one-thirding the last bet.
Player EV was +.30%. Win rate was $12.50 per 100 hands. SD was $874 per 100 hands -- a very poor set of numbers. The betting ramp began increasing at +3.5 TC and reached 30 units at +8 TC.
Would like to see what some others come up with.
