Number of hands to play

[Nitram]

1. In Professional Blackjack and BJA3, playing heads up, we should play 1 hand until we're capped by table max, then we spread to 2. When I compare the sims in cvcx, playing one hand heads up doesn't seem to generate the same EV as playing 2 hands, heads up, at a true 2

I believe the spread at the time was:
1x75
2x75
2x150
2x225
2x300
2x375

Compared to
1x75
1x100
1x200
1x300
1x400
1x500

When playing 2 hands, each individual bet would be 75% of what the corresponding single-hand hand is below it.

So, for example, at a true six or higher, I should play 2 hands of 375 or 1 hand of 500.

The results are playing 200 rounds per hour, h17, das, rsa, sr, using hi low variant, I get:

170 an hour playing 2 hands at 1.8%RoR compared to

130 an hour playing 1 hand at 2.1% RoR


Both books claim more EV is to be made by playing 1 hand.

Even when I boost the 1-hand sim to 225 rph I get 145 an hour.


Any ideas on what option i could be forgetting about?
