Tough to say, as I’ve not seen any manufacturers who use the Sniper system disclose how much adjustment they have.
It doesn’t translate directly, but CRG and other brands who use the sniper system also have an eccentric pilthat can be used to replace the central pill on the underside of the “c”. The rule of thumb I’ve always used is that the CRG eccentric equates to two “lines” of adjustment on the sniper system. With that being the case, the sniper system allows for around 4 lines of adjustment in each direction, so 2x the eccentric. In my time running karts with the sniper system (CRG, DR, TB) I’ve never needed the full range of adjustment.
The 5-6º of adjustment you mention is an absolute crap load, and I could only ever see using the full extent of that in the wet. In dry conditions 1.5º is a big change.
