Re: Stus-List converting TOD results to TOT

[Michael Brown via CnC-List]

PHRF Lake Ontario has the ToT multipliers listed in tables:

http://www.phrf-lo.org/index.php?option=com_content=category=81=198

PHRF-LO uses 566.431 and 401.431 for A and B, seems to be different from 
everywhere else.
That has the effect of setting the scratch boat at 165 which is fairly high, 
and "slow" boats get
more corrected time.

As an example, if in San Francisco two boats with PHRFs of 171 and 228 each 
raced for an hour
they would correct to 3245.4 sec and 3007.8 sec. A delta of 237.6 sec, about 4 
minutes.

On Lake Ontario it would be 3562.2 sec and 3239.64 sec, a delta of 322.56 sec 
or ~ 5 1/3 minutes.

There is always an interest comparing PHRF ratings between regions, but when 
the ToT correction
can be so different I suspect it adds another consideration.

In San Francisco we use the same formula.  650 and 550 are the numbers. 
Works here!

Re: Stus-List converting TOD results to TOT

[Edd Schillay via CnC-List]

Pete,

What is your TOT formula (it’s different in different places)? 

We use C = E * (600 / (480 + P)) 

Not everyone uses the 600 and 480 numbers. 

All the best,

Edd

Re: Stus-List converting TOD results to TOT

[Hoyt, Mike via CnC-List]

Note to any interested.  I have such a spreadsheet and sent one copy to Pete 
off list.  Is available to anyone else interested.  Also a copy can be 
downloaded from www.sailnovascotia.ca<http://www.sailnovascotia.ca> under PHRF 
racing downloads although the one I have here is a bit more detailed.

Another option of course is to download and use Sailwave.

Why not just use sailwave and select the appropriate  scoring system?

I’m trying to save myself some time and not reinvent the wheel:  Does anyone 
have a spreadsheet for converting race results from TOD to TOT? From the 
results I have PHRF rating and Elapsed Time in D:HH:MM:SS format.   Thanks, ___
