Totally agree with you. Stemming from that, though: Is it possible that one race has a higher varient than another race on the same day, even absent extraordinary, intervening weather conditions? Put another way, could a race earlier in the day be on a "faster track" than a race later in the day? The reason I ask is that the answer to that question impacts whether to apply an entire daily varient, as an average from each race's varient, equally to all races, or instead to apply each races varient to each individual race and no others (e.g. no averaging or general application to the entire day's races).
And going one step back, in order to calculate the varient, must you use class and distance pars? While Mr. Carroll seems skeptical of their accuracy, I can't see any other way to actually calculate a variable. I can't see how the track record time (or average of 3 fastest times over X years, etc) could help determine if today's races were run on a "faster track" than yetserdays races (or, more specifically, if race 1 today was run on a "faster track" than race 3 today).
