Am I doing TOT wrong?

I’m new to Sail Wave and pitching using it to our club as another way to score our regular racing vs regatta software companies.

But…we use PHRF TOT. And the math is not coming out correctly for corrected ET. I would also like to include a column for ET.

I’ve double checked my entries…and no boat is correct on a scored race.

The TOT factor I calculated and input on the competitor screen. It represents 550+HCP/650. The confusing part is the race scoring screen for HCP system indicates PHRF tot and separately the 550/650 numbers to be used. For this to work, sailwave should use the TOD rating and the TOT factors to make the resulting TOT HCP multiply times the ET. It appears to be doing it twice. Ordinarily I would put in the TOD hcp on the competitor and the system would calculate the TOT and multiply that by the ET. But it doesn’t?

I’m in audit mode. It would be nice if the audit page showed its math.

Lead me to my mistake. Thanks!

Hi Bruce,

Would you be able to share the sailwave file?

Here is the file I built as a test.

Bruce,

I am no expert in PHRF, but your rating values seem wrong to me. The PHRF of a J24 is around 171.

There is a test area to calculate handicaps.
See below:

So Im supposed to put in the TOD number on the competitor.

We use non spinnaker ratings from phrf.

Here is the comparison scoring.

I changed the entries. Not sure how you managed to pull in that boat for the test.

Here is the new file.

I didn’t pull the boat’s data in, I just entered the data manually.

When you publish the attached file you can see some of the additional calculated values like speed, back calculated rating, etc.

It isn’t calculating correctly. Compare with my screen shot.

Hi Bruce,

Firstly welcome to the Sailwave User Group.

Having had a quick look at the file Peter returned to you the main problem is that the A value should be in the B value box and vice versa. I acknowledge the corrected times are not exactly the same as in your screen image from a different results system. I will look at that later today.

Kind regards,
Huw

I was able to match your corrected time of the J24 when swapping the A and B values, both in Excel and Sailwave.

Peter

Just to be sure… the formula:

650/(550+TOD) X ET= Corr

Thank you!

One other question…can ET be a display column as well as CORR? I didn’t see the option.

Bruce, you can display those values any many more at the race level.

See below:

One of the strengths of Sailwave is the ability to use Javescript to enhance the results. You can have scrolling results with a sponsor sidebar overlaid on random images displayed on smart TV’s. Your imagination is the limit. Many of us have spent time enhancing the view of the results.

I hadn’t gotten that far in the instructions. Great!

I got hung up at the math level.

I just reversed the A/B and now am all good!

I was confused by entering the TOT handicap on the competitor and then having the formula backwards. The double error was messing with me.

A “hint” example of the correct A & B number next to the boxes might be helpful next update. :grinning:
