Ha. This rule is f÷/×ed up the way its enforced. First, average fan doesn't understand concept at all - especially since so rarely enforced. So when some n ag is taken down it really pisses off any folks who thought they were winners.
Amusing in this instance though. Isn't a 29 quarter in the Slop a blistering pace at Monticello. 
Probably wasn't the pace that caused jam up. Maybe some horse hit one of the potholes on that track. Or hit a wine bottle thrown by one of the drivers.
Watching Kyle D's hands on video, didn't look like he grabbed in, more along the line that once he cleared down the backside, he wasn't chasing to get to the front.
So I watched a couple today, there was a race that the front runner did appear to grab in, quarter in 28.3 and backed up to 31.3 second quarter that sent one horse to the outside abruptly and one dove to the inside until everyone got settled. NO CALL
Still out on my thinking about the whole rule. You can't judge by time. A driver could grab in and get someone hurt in a matter of 50 yards. On the other hand if it is a slow quarter and everyone remains lined up -- then freakin pull.
Again -- just found it interesting that the judges called this one a DQ --- maybe studying the fraction times so much they didn't catch a couple of 5's in the same race
