I just heard back from Vic, the following is from Moss. instruction sheets.
#4 site is 1/8 min. so would be 1/8 @ 100, 1/16 @ 50, 1/32 @ 25.
S-100 & 130- 1/2 min.@ 100 , 1/4 @ 50, 1/8 @ 25. Sorry for the mis-info, I would have checked first but your question was up for couple days with no response.
