Unfortunately SFR doesn't offer the STR class. I think there's a bit of
an anti-ST bias; most of the time the region's approach is to follow
the National guidelines to the letter.

Regarding your numbers: The STR index looks pretty reasonable, but 1.6
seconds slower on a 60-second course would equate to an index of about
.793, right?
60 seconds x .814 = 48.840 indexed time
(60 + 1.6) seconds x .793 = 48.849 indexed time
With the RTP .774 index, to get the same indexed time on a 60-second
course would require a time of 63.1 seconds, right? What am I doing
wrong here?
How did you come up with the 1.6 seconds?
