Beyer Questions???????

[Ogygian]

I need a little bit of help regarding the Beyer speed figures....
What exactly does a horse have to do to get a Beyer rating more then 120? Let alone more then a 115??? Quality Road shatters a track record and only gets a 110? Rachel just misses and gets a 116, Fabulous Strike just missed Artax's track record and gets a 111 ( Groovy set the record and gets a 133 or 132).
The highest Beyer the last 2 years is a 120, set by Commentator in the Whitney...which was the slowest Whitney in 42 years. Just doesnt seem right...
Is it just me or are the Beyers getting slower? Records are still falling, training is more advanced...Why are there only 2 Beyers over 115 this year?
According to the DRF the Beyer scale is as follows...

57 +- Bottom level $2,500 claimers at smaller tracks
80 +- A typical $10,000 claimer
90 +- A typical $25,000 claiming race
100 +- Good allowance horse or low grade stakes horse
115 +- The best horses in the country

So....Quality Road is a "Good allowance horse or low grade stake"? Same with Strike...I guess the same with every stakes winner this year...Derby, Preakness, Belmont...Low grade stakes????
And only Rachel and This One's for Phil are the "Best" horses in the country?

Is it possible the claimers, maidens, allowance horses are getting faster?

I look back and see a 128 for Ghostzapper, Groovy gets a 133 and 132, Lava Man 120...

Are we ever going to see a number over 120 again?
