The Second Time Lasix Angle

[Turfday]

I've never paid much attention to this angle and wondered if any posters had any strong opinions one way or another. Just for the sake of argument or fact, I posted some trainer stats from my database on this angle. Any general thoughts and if you feel this is an important angle in your handicapping?

Suff,

I get the feeling that prophylactic use of lasix is so wide spread that unless you could cull out the individuals that really needed it, the angle would be useless.

As an exercise, I looked at 2nd time lasix of the whole population of my database vs. just 3YO fillie races and saw miniscule difference.


Whole population:

Code:
Strt Wins Pct. IV ROI
2nd Time Lasix
Yes 16422 1959 11.93 1.01 -0.26
No 442293 52479 11.87 1.00 -0.24
3YO fillie races:

Code:
Strt Wins Pct. IV ROI
2nd Time Lasix
Yes 2127 262 12.32 1.00 -0.22
No 25987 3208 12.34 1.00 -0.24



Possibly looking at specific trainers, to isolate trainers that only use it when needed would be a productive angle to pursue.

Data on 3rd time use not as easy to get.

I am no expert but I have read that 2nd time lasix can be more effective than 1st time because trainers don't always get the dosage right and other reasons.
I've read that for fillies for some reason 3rd time lasix is a valid angle.

Look at it from the horses viewpoint, he/she don't know what they injected, but hey, he/she stopped bleeding, thats got to feel GOOD, next time out who knows ?
