if you know the potential is high on FSS, its 21+. low high is 21-27 and high high is 28+, if you had gotten the scouting report. its hard to say without, lp and per work differently than the other ratings. most other ratings couldn't go from 20 to 100, but lp and per can. you could see anything from +21 to +80. obviously, its most likely on the lower end there, 25-30 is a pretty reasonable thought, but there's also the outside chance the guy ends up at 80-100.
