Have posted mid-chart version but can easily make t-precision system is compatible with the ACBL’s General Convention Chart. 

 Haver educed the requirements for a 1♣. opening to 16+ HCP unbalanced or 17+ balanced. Could also be good 15-16 HCP with 5M332. Limited openings are for the most part now (10)11-15 in 1st & 2nd and 12-15 in 3rd & 4th with opening light possible in 3rd except for  2♦:.1NT  is 14-16 HCP except for NV 1st a nd 2nd when is 10-12 HCP.

 Have  allowed some 4 card major positive responses to 1♣. Namely 8-13 HCP 4432 dist.(with a major) or 4441 dist. 8+ HCP. This means that bids are not required to show rare 4441 hands, so 2♥/2♠ are contructive pre-empts 4-7 HCP.  2♦ is used to show balanced hands 4333, 4c4d32 or a weak 5 card minor 8-13 HCP. After 1 level interference, all suit bids show a 5-card suit, 1♠ (or double of 1♠) shows balanced hands(may have weak 5 card minor) 8-13 HCP.  Contructive pre-empts 4-7 HCP are available over  Double (2♥ multi),  over 1♦(2♦ multi), over 1♥(2♥ for spades)and over 1♠(3♦ for hearts). A trap bids 1♠ or doubles 1♠. 4441 hands 8+ HCP bid 2♥ over  1♦, 2♠ over double, 1♥ and 1♠. Have switched the 2NT bid with the 30/14 ask over a 1NT(clubs) and 2♣(diamonds) response, this will make it easiear to find 4-4 major suit fits.

have used 3014 as the main asking bid replacing Beta which should be simpler.  Reworked keycard responses (including switching to 3014 from 1430) to be clear.
