L190, S3: 1.1 (0.8).
I would just have assumed all three types have the same scaling factor... anyway, there didn't seem to be any numbers that wouldn't fit a value of 1/25.
I've got one really weird one, but most of the values are in the range of 20-30 with one or two outliers. They probably do have the same factor, I just need to look at the numbers more closely and check.
