[Retros] Add units, 20th update

[CAILLAUDM at aol.com]

Hello Mu-Tsun,
 
A reason not to include everything is perhaps to avoid explosion of records 
 and lot of work more for Alain.
For example, for 2A category a lot of "sub-records" can be defined  : 2KKA, 
2KQA, 2KRA,...
 
Anyway, if some are interested I can give here my versions (though 4A  and 
5A are rather stonesteps to 6A than anything else).
 
3A
8/P1P5/1QPB4/3P4/PP2R3/k7/N1PP4/K7
 
4A
8/P4pp1/PB6/BPB5/k1K5/B1R5/2PP4/Q7
 
5A
8/pp1p1ppp/8/K2P4/1PkP4/Q1B1Q3/P3P3/2Q1B3
 
PS : congratulations for the most striking find of the serie (Rd1 in  1RA)!
 
Best,
 Michel

Personally I  don't see any reason not to include everything. Certainly 
people will be  interested in "how many units is needed for forcing a 
particular number of  units to be added" that kind of thing. So I'll 
encourage you to keep  tracking the records for all the entries in the 
table.
