A track that is factored at 3000' could see local current weather that was actually closer to 1900'. Since they don't adjust the factored indexes to account for that, it'd be ludicrous put HP on a car for running 1.25 under the factored index.
If a car were to run 1.250 under the sea level index, then of course, it needs HP. But it already works that way now.

Alan, if, and it's a big IF, the altitude factors currently used are correct, a -1.25 at sea level should be the same as -1.25 at altitude. When east coast racers accuse some altitude records of being "bogus", we're called crybabies, and that the factor system used is correct and nothing bogus about it. There were a few records set at Boise a few years ago. Boise's physical elevation is something like 2,800'. The corrected air was much lower than that. One racer reported 1,800'. But the track used the 2,800' factor, and records tumbled. BUT, many cars at sea level, in conditions close to the DA at an altitude facility, don't run anywhere close to the factored record from altitude. Now, does that mean the factor used to equate records is incorrect, or are they sandbagging to not receive HP, or something else? I always equated racing at altitude as "having your cake and eating it too". Run fast, and almost never receive HP. If the factors used really are correct, then a -1.25 at sea level (Atco) should be no different than -1.25 under at altitude (Denver), and both should receive equal adjustments.
B/SA, sea level Index 11.55 (old index). You run 10.150 or quicker (more than -1.400), you get HP.
B/SA Boise Index, 11.93 (old Index). You can run 10.151, which is -1.779, but results in NO HP, because the car didn't run -1.40 under the 'sea level' Index.
If the factors are indeed not a little suspicious, then a B/SA that runs quicker than 10.430 (more than -1.40 under that particular adjusted Index) at Boise should receive HP.
Am I missing something?
