I've never had one of mine abused so I can't predict how I would react if my jockey was done and the horse disqualified. Judging by the scenes in the betting ring last week, I'd like to think that it would be with more grace than shown by your average punter. I'd certainly take a different view to 'abuse' of a young/immature horse compared to a seasoned pro.
Just so that everyone is talking the same language, this is the PJA summary of the regulations:

The first point that I'd make is that, for me, this is a subjective issue in the sense that it's the subject of any abuse that is most important. However, it's also subjective in the sense that evil, like beauty, is in the ye of the beholder. In that secondary meaning, I find it ludicrous that the same whip rules apply to a 2yo having it's first run as do to a 10yo chaser having its forty first. I'm guessing that the average flat race distance is about 7 furlongs compared to maybe 20 furlongs over jumps so to have the whip thresholds at 7 and 8 respectively is wrong. Now I'd be in favour of banning the racing of 2yos but, if it must be done I'd like to see the whip threshold be much reduced to, say, 3 strokes. On the flat, for 3yos it could rise to 6 and older horses could stay at 7. For NH racing, bumpers and races for 3yos and 4yos only could work with 6 and older horses rather more, say 10.
The whip is a vital piece of race riding steering equipment and I'm not sure that it's realistic to expect jockeys (of all people) to be counting whip strokes under penalty of losing the race. The manner and placement of whip strikes is, for me, more important than the number.
