You do realize that in PHRF whether ToD or ToT you are racing the clock and not other boats.Our club considered switching to ToT a couple of years ago. Ran some test on past races and it didn't make any difference. I think one race had one boat move up. As a competitor, it is nice to know that you need to cover a 3 minute 15 second handicap and not have to calculate it as you would with ToT.
That is just silly.You do realize that in PHRF whether ToD or ToT you are racing the clock and not other boats.Our club considered switching to ToT a couple of years ago.

If you can beat your Time Allowance you are going to probably win if other boats do not.
PHRF is a race against the clock.
OD is a race against other boats.
It's like someone said ToT tightens things up a bit where ToD is for those who care about knowing something they cannot really change.
Correct. Its not perfect, but I think ToT is the more flexible of the two methods that accounts for more variables.TOD makes no sense at all when courses need to be shortened or wind strength changes noticably
BC is known to march to its own drummer regarding ratings, and the premier BC event, Southern Straits, is ToD. With rating bands around 30 seconds.British Columbia uses TOT with a B factor of 520, have since the start. Keep the divisions under 50 seconds, ideally under 30 seconds, apart, works better, but that is true of any PHRF system.
Interesting points.Turd Sandwich said:Large rating bands are the problem and i think they are worse with ToT especially in light air(course takes longer to complete) If you have a rating spread of say 100 seconds plus TOT will favor the slow boat about the same as it favors the the fast boat in TOD in 12 knots of breeze. In the light the fast boat will have to cover almost twice what it would have time wise to cover in TOT in say 5 knots. That does not happen in TOD.
They both suck with large splits. In the light TOT sucks way more for the fast boat.
Tighten up the splits to say 20 or 30 seconds and both do an ok job and its back to horses for courses.
The rise in popularity for TOT comes down to one thing only. The race committee can be lazy fucks with TOT as no distance is required
Can you elaborate on this a bit? (not questioning your assertions, but would like to understand more what you are saying)Lake Ontario uses TOT but they have so completely distorted the individual boat ratings and the TCF formula that you really can't call it PHRF.
ToD is not "completely screwed" in current. The negative effect you are suggesting is based on time not distance.Problem with ToD is it is completely screwed when there is any current. (and in most places there is some current)
Depending on the current, the distance sailed by small boats can be quite different to that sailed by larger boats.
There seems to be a bit of "we use ToD because we've always used ToD". A reluctance to learn or try something different.
