XG cube analysis -- Methodology question

In practice, in money games, other than last roll positions, take equities will typically vary between about 0.56 and 0.62 (multiply by cube value after the double) depending on the proportions of gammons. In blitzes, where the taker will suffer a high proportion of gammon losses whilst winning few, the take equities will be near the highest end of the range.

The theoretical background to these relationships is set out in the 1990s paper "Take Points in Money Games" which you can read or download at the following link:

Refer to table 2c for a quick summary.

Prior to this work, previous documented analytical approaches had assumed typical take equities of about 0.57 regardless of gammon and backgammon percentages. The release of the first commercially available bots a year or two after this paper, provided independent verification through extensive rollouts, that take equities can and do exceed 0.600 in early blitz doubles and similar skewed gammonish games.
