The other day, I opened up CVCX and looked at the included sims "HiLo Full Indices" and "HiLo Lite Full Indices". I found that the data within the two sims looked bizarrely different, and I've made a couple of Excel charts showing the differences.

This chart shows the Win/Loss numbers from the two sims:

For counts of 1 through 5, the Lite Full Indices sim says that the advantage is more than twice what the Full Indices sim says. That's a huge discrepancy!

The frequencies are vastly different, too, with the Full Indices sim showing high counts occurring much more frequently than the Lite Full Indices sim:

The only explanation I can think of is that these two sims are using different counting systems even though the titles indicate that both are using the HiLo system.

What's going on?
