You're quoting his OR and the official handicapper. What that has to do with his Timeform rating is beyond me.
True. Only idiots question Sea the Stars greatness.
The point I'm making should be obvious. There is a descrepany is whopping. Even according to Timeform's exaggerated stretching of some of there own ratings on this scale (it is the same as ORs on some other ratings) this is too much. This I repeat was due to them adding extra pounds to the rating for ease of victory (something their own methodology states the + and Ps are for).
That's incorrect. Not that it would mean anything if it were true.

I'll try this again: it has already been established that the level of Timeform's ratings are higher than ORs. This is, in of itself, irrelevant, as long as you compare like with like.
If you do want to compare them, you need to take into account Prufrock's research, which showed that Timeform Ratings are around 8lbs higher than ORs on average, although it decreases at the top end. That does not mean they're uniformly higher. There will of course be bigger and smaller differences, as there should be, as different methodologies and different opinions are factored in.
In Harbinger's case, the official handicapper rated him at 135. Only 5lbs lower than Timeform's figure. So in that particular case they're actually pretty much in agreement as to how good that performance was.
What I’m saying is that Prufrock has tried manfully to square the circle, but when Timeform does not even apply its own methodology consistently I think we have a right to challenge such very inflated ratings. TF has both climbed back from its original 142 to 140 and admitted that it has added in extra pounds for ease of victory. This is something that Timeform did not do in the past (it is what the + and Ps are for). That it has decided to do this now (I can only conclude to put a spin on such headline horses) is wilful manipulation of the actual rating.
i'm confused as to how ratings can differ by 8lb using the same scale.
if that is the case..stating a horse is a 132 TF animal..then maybe in brackets we should have the OHR just for clarity
But if one is 8lb higher than the other, you would need to adjust accordingly before making comparisons.
But wide margin winners usually aren't driven out, so we might not see the full extent of their superiority. Its swings and roundabouts.

It's not the case that one is 8lb higher than the other though. With many horses (even at the high end) the ratings may be 1 or 2lb different sometimes identical and at times the ORs or RPRs can be higher. Difference will of course occur. But this 8lb higher business is a smokescreen. It is so imprecise that you could drive a bus through it.
They are not the same scale. This is a common misconception.
Of course it is imprecise.
If either organisation tried to standardise the gap it would be doing the wrong thing. Each should only concern themselves with their own metric.
But on average the gap is 8lb or so. A bit smaller for higher rated horses (6lb I think?) Comparing them is futile, unless you recognise that ratings are on average higher in Halifax.
Perhaps we could put them to the test by looking at what happens to wide margin winners subsequently. I think they get overrated. I haven't tried to measure it in any systematic way, it's just an assumption I use when analysing form because it seems to work..
