Doesn’t sound EZ to me.

Dennis,
ORR EZ is much more sophosticated, using VPP predicitons and ratings for
different courses and wind conditions. It should be more fair.

Hi Dennis,
No experience with ORR-EZ yet, but it looks like another good option by which
to score mixed fleet races (i.e. not one-design fleet races).
Last year Colorado Sail & Yacht Club experimented with National Handicap for
Cruisers (see https://www.rya.org.uk/racing/pages/nhc.aspx). We still used
PHRF as the official scoring system, but also scored the same races by NHC to
see the outcome of applying a different scoring system to the same race
results. We could do the same with ORR-EZ.
The proponents of this idea were looking for a scoring system that is more
“fair” than PHRF. I liken NHC to golf handicapping: your handicap changes with
every scorecard you turn in, conceptually. So it dynamically reflects
variability in weather conditions and crew performance, which a static PHRF
rating doesn’t. ORR-EZ appears to have some similar elements (observed
performance factor, configurablity per race course, etc.) which in my opinion
are valuable.
With a 30 MK I my results in my fleet are generally dependent on wind
strength. The stronger the wind, the better I place, all other things being
equal. In light air boats with less displacement beat me. It’s almost as if
boats should have different ratings for different wind speed ranges.
On a related note, my RSA is re-rating all boats in its region this year, and
Grenadine’s PHRF rating is likely to come out 12 seconds lower. But at least
one of my competitor’s ratings will stay the same - which exacerbates the above
problem, unless we have a really windy season. I think I’ll start a separate
thread on 30 MK I PHRF ratings, because I see 18 seconds variability across
RSAs.
Cheers,
Randy

What's folks experience with ORR-EZ so far?
