Pretty sure it's twenty still. Now it'll drop numbers off the bottom whenever it over fills.
Example:
19) 664
20) 452
Number added to top:
19) 344
20) 452
Anyways it's not normally a problem, as you add SG conditions like *.robage sgn you can simply mult them together. Normally I try to keep all my conditions equaling 1 for true or zero for false just to keep things straight and the dna working properly.
Ie.
' repro when nrg > 3000 and eye5 < 45
50 .repro *.nrg 3000 sub sgn 0 floor mult 45 *.eye5 sub sgn 0 floor mult
