I've made following diviation:
-8 or 9-carder with a 3c other = 8311 or 8320 or a 9310 distribution
-no 3c other and 11 or 22 in the "standard" extreme 3 bid ( = normally 6+/5+ but now 11 or 22 with the 8122, 9211 or 9022 distribution)

further relaying:
in this way so that you can stop always on the correct maximum level for the given suit with a minimum.

Exact distribution: each shape separate and within the shape numerical
so for the side 3c shapes the order is 8311 | 8302, 8320 | 9301, 9310
and for the side shapes with NO 3c the order is 8122 | 9211 | 9022

(for those 8/9-carders the % = 0,4545, with a 3 card = 0,2361, a 9 carder 0,036%, so you will be able to handle the 8 carder in a good way, that means a relative "low " bidding level

to give you an idea how to proceed.

But no further working outs will follow because I prefer the 8 and 9 card diviation regarding knowing the s/v for the 8 carder on a very low level (Delta openings). In this way the "more" common 8 carder can be treated in the best way.
