PHRF Lake Ontario has the ToT multipliers listed in tables: http://www.phrf-lo.org/index.php?option=com_content&view=category&id=81&Itemid=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.

Works here!
