Brief Review Of The Formula

I'd started on FR in early 2008 considering each of the 3 variables but did so at that time in terms of "bone remodeling". What would/would not cause "remodeling when we sent the horse out there. The term FR came later.
And, this interesting sequence from the 2/11/08, exactly 2 years ago when this subject coincidentally was started:

"For discussion purposes, let's note some possible approaches to working for the Derby. Assume each of the below contenders races at over 1 mile once a month to Derby time. Here is the breezing schedule for four of them:

1. Frankel's :48 once a week.
2. Drysdale's 1:45 mile every 10 days with plenty of 2 minute licks and accelerations in between.
3. Mandella's 4-7f :12.5/f works every 10 days.(2011 note--somewhere along the way I guess it was decided Mandella goes every 7 days. Probably he's inconsistent.)
4. Pletcher's 5f in 1:02 for three weeks, then race, then 3 weeks of no works and start again.
Quite a contrast there if you look at it closely. I'll give my answer in advance that "none of the above" is truly effective for fracture resistance and give my reasons, and get to Burch and Carl Nafzger and Street Sense next posts."

"None of the above", lol, and now I am touting Frankel as "sufficient". Probably my thinking in 2008 is that Frankel and racing only once a month and then the Derby that 4f is an insufficient distance. More on this a little later.
First, the formula:
4F in 12/5 sec./f every 7 days = FR
and a brief review of how I arrived at the first two variables.
Minimum speed I ferreted out on two basis and think I am very comfortable that I am absolutely correct. One was stride differences as the horse changes gears from :15s to :14s to :13s, and then to :12.5. Guarantee you'll see a significant increase in concussion from :13s to :12.5 if you watch your horse closely in it's work. There is a transition there somewhere between ground flicking and ground pounding. I think it logical that some pounding is required for FR. The second thing was my own subjective experience being on horses at speed. Again this involved where you cross over from failing to feel the thud of the hoof to ground and you start feeling and hearing it when you're on board. Again, the cross over is between :13s and :12.5.
Thus, in terms of Bill Pressey's comment proposing 2 breezes a week--one 2-4f in :12s and the other 6F or more in :13s-:15s--if the horse does less than 4f in :12s, will it get there? As the formula is in minimums, "no" is the blunt answer, but, more discussion coming.
Training:
The knee bump was bigger and hotter Thurs. night then it was when I first diagnosed it on Mon., but by Fri night it had receded very significantly. Decided to give it to Sunday. Want to avoid doing any work on what might be a flayed membrane holding in hylraunic acid. The weather started 1/10 so we're about 34 days of very little training.
