It looks like the 1,...,2 openings can more or less be obtained from classic Precision's 1,...,2 and 2N openings by first shifting ranges upwards by one (if BAL) or two (if unBAL) points so that

1 = 18+ any
1 = 12-14 BAL OR 12-17, unbalanced with either 5+ D, 4D5C, 4D(441) or (41)35
1M = 12-17, 5+ M
1N = 15-17 BAL
2 = 12-17, either 6+ C or 5C4M
2 = 12-17, "4415 minus 1 card"

and then moving

* all 4M3-OM hands from 1 to 1
* all 2245/(31)45 hands from 1 to 2
* all 4414 hands from 2 to 1
* all 4405 hands from 2 to 2
* all (BAL) hands from 2N to 1
* all strong (18+) hands that are neither balanced nor 2-suited with at least 5-5 from 1 to 1.
