I understand that John, but it gets confusing for people who don't understand SCHRS and who expect Stealths to be one design! Particularly if someone enters as an F16 but wants a bigger handicap than the handicap that the SCHRS list would imply is correct. I've had loads of hassle at my club getting handicaps for our Stealths sorted, particularly as one sails in a very strange configuration (F16 main and the original, tiny jib) having previously sailed as an R with the original main and an R jib. It doesn't help that our racing is run under PY so we have to come up with a conversion factor too.
