When I've done P&R in the past, I have on occasion had riders argue, or
try to get the out-time "adjusted". The most common arguments were that
my stethoscope readings were wrong because they were different from the
HRM readings (my understanding is that the HRM counts the beats for
several seconds and then multiplies it to get a "per minute"
count---which is what we're also doing when we count for 15 seconds and
multiply by four, but counting for 15 seconds is more accurate than
counting for five or ten seconds. Maybe Roger can verify.) The other
argument is saying at a busy check that they've been yelling for a P&R
for "two or three minutes" and therefore that time should be deducted
from their out-time. Luckily, this argument was easy to beat because in
every instance the horse just barely squeaked in at criteria and so even
if they had been waiting two or three minutes, it was unlikely that
their horse would have been sufficiently recovered, anyway.
To be fair, however, the majority of riders, even those running up front
where a minute made a difference, didn't argue. The two riders (a man
and wife) who habitually try to get somethin'-fer-nothin' at the checks
have a reputation in the SW of not being particularly good sports and so
I imagine were just playing true to their nature.
