In our meet yesterday - officiated by someone that appeared to be very sharp on his Canadian rules (certainly sharper than me) - we had a fairly strong tail wind blowing.
There were several cases where the pole knocked into the bar - sometimes knocking it off, and sometimes just sliding sideways and lodging onto the standard on one side or the other. There was a pole-catcher assigned, but the head PV official asked her not to stop poles from hitting the bar.
What seemed to be rather unusual about this meet was that there were so many instances of the pole sliding down the bar to a standard (especially the vaulters in the 2.5-3.5 meter range). There were more cases than usual of the pole hitting the bar, but less cases than usual of the pole dislodging the bar. i.e. The bar was quite "sticky" on the pegs - it did not dislodge easily.
If the bar went down, it was a miss. If it stayed up, it was a make. Simple as that. Altho I don't know the exact (Canadian) rules re this, there did not seem to be any concerns or complaints from anyone.
Re calling it a miss if the pole passes under the bar, I think that would be just as unfair as calling it a make when the pole would clearly have passed under the bar but for the fact that the pole was longer than the bar ... and slid down and lodged onto a standard.
My vote is to NOT catch poles that might hit the bar in a tail wind. Let the poles fall where they may, and if they knock off the bar, then it's a miss. (As per yesterday's meet.)
BTW, a little off-topic, but I question the sanity of human bar-holder-uppers in a heavy tail-wind. PV doesn't have a wind guage for records (does it?), but in light of that, if the wind is so strong that people need to manually hold the bar in place, then I say the wind is too strong ... at least too strong to recognize any records set.
I say this not just becuz the holder-uppers can be considered a rough guage of a maximum wind speed, but also becuz it becomes problematic to determine if they let go of the bar JUST BEFORE or JUST AFTER the vaulter passed over the bar ... especially if he SCRAPED over it (I would venture to question the impartiality of some holder-uppers - some are obviously there to help the vaulter clear the bar, and have a vested interest in the outcome).
In that scenario, how can an official differentiate between the wind blowing the bar off or the vaulter scraping it off?
And how can you tell if the holder-uppers didn't hold the bar in place whilst the vaulter scraped over it hard enough to dislodge it?
So what do you do if the wind is blowing so strong that human holder-uppers are needed? I say any of these attempts are UNOFFICIAL, and should not count towards a record ... or even towards the outcome of the meet. This may be an unpopular opinion, but I think that you should have wind delays until the wind dies down ... just as you have rain delays.
