Adjusting Ratings (Personal Handicaps)

New to the software, liking it more than the others I've seen, but I'm having problems getting my head around the ratings/handicap system.

Using the example series "startfinish.blw" and I can see that different competitors have various ratings within the same class of boat - as you'd expect.

I am changing the rating system to PHRF. I am then editing each competitor and assigning them identical vessels with a PHRF number of 60 from a table I've entered.

I then click the "Score series" button and the positions are tallied and all looks fine, aside that I would expect each compitors rating to be adjusted according to their performance - which is not happening, their ratings all remain at 60.

So what am I doing wrong?

Hope you can assist me here, this software looks like it could do exactly what I need and is by far the most user friendly I've seen.

Cheers, Steve

I think you have a misconception about how PHRF works. PHRF assigns a rating to a particular type of boat, and all identical boats will have the same rating, irrespective of the experience of a particular skipper. So if one skipper beats another in identical boats every week, the handicaps don't change. The performance is taken into account for the class of boats as a whole, so that if a type of boat seems to be performing better or worse than its handicap, the local PHRF handicappers may decide to change its rating - for all boats of that class.

I hope this helps!

Yes, you're right on the money there.

I guess I should have asked simply how the personal handicap system should work with Sailwave.

I'm trying to build a system which brings the corrected times of a fleet of disparate boats closer together based upon past placings. Kind of like PHRF but with a crew skill modifier.

I can't get my head around the custom ratings setup. I want to attempt to tighten the bell curve of a fleet.

My thought is to see the top & bottom 15% of fleet average time dropped, then 25% of the difference between competitor and fleet elapsed time (averaged over three races) applied to each competitor.

In an ideal world this would mean that over a season each skipper has a chance to win at least one race (regardless of how old/slow his boat) and the better skippers would have to push harder to win on corrected time.

I can do this in a spreadsheet, but it's too hard to train an operator and it lacks the other features I admire in Sailwave.

Hope you can help me out here :slight_smile:

What we do is to average out the BCR's provided by Sailwave over a season, and then use that as the boats PY for the following season. Now you could make that quicker by averaging the BCR's over a series then using the resulting PY for the following series.

I do have an application that you can publish a Sailwave series to that will provide a table of average BCR's

cheers
