Preps for next week. World Record
 on 7/8 is 150 4/5.

If I am not mistaken, the North American records for different-sized tracks for trotters (all ages, both sexes) are:

Plunge Blue Chip 1/2 mile track Delaware 1:51.3 5yo mare
Sebastian K 5/8 mile track Pocono 1:49 8yo horse
Lexus Kody 7/8 mile track Woodbine 1:49.1 7yo gelding
On To Norway 1 mile track Meadowlands 1:48.3 4yo gelding

Allegiant's World record of 1:48 was in the $1mm Elitloppet Final at Solvalla (which is a 5/8 mile track.)

Only in the horse game people just do back of the envelope math and make everything sound like sunshine and rainbows while, in fact, it's anything but. You conveniently forgot expenses which started the moment the hammered drop and believe me, don't end. And the plane ride home is 30US, the insurance to get him off the premises is 3% alone and it goes better from there. I agree with your assessment of the mares and what the stud fee may look like but getting their money back in three years is  never going to happen.

I think I accounted for that and more since I was assuming $5.25mm GROSS in my hypothetical whereas the hammer was $3.7mm, so that would cover insurance, plane, farm maintenance for another stud, advertising etc. of $1.5mm.  Key is fertility.

You were close,  153 2/5.
