Yes, atmospheric pressure is 15-16 PSI. But, the downstream side of air pressure gauges are set to open air; correct measurement is PSIG, with "G" meaning, obviously, "gauge". After all, air at atmospheric pressure is pretty useless in machinery.
But. . . ONE HUNDRED SIXTY FIVE PSI? No way would I ever allow it, and there's nobody on the planet who can MAKE me allow it. many times the opposite of "safe" isn't "unsafe", it's "stupid."
'Nuff said about that.
Timing less than a second? For the love of electrons, people, quit whining about timing. As Fleet and I have mentioned countless times since the Amish had an unfair technology advantage, there is an incredible difference of response time accuracy between a totally random event and and watching/waiting for an expected event at a specified time. There's another difference between stopwatch operations by experience level. So, statistically (yes, I've collected data on this over the years), the 59-61 second machines will have the best timing, while the 6 second and the 165 second times will have the most inaccurate results-- quite the opposite from what you'd expect.
That's why I always, always, always ask detailed questions about how any timed portion of their device runs, if it stops slowly/quickly, noisily/silent, smoothly/erratically, etc. After a thousand times, you get good at it.
That one year Mission had to have a timing circuit put in, it was quickly determined that there was no appreciable error between "automated time" and "judge time". I had THREE that were off by more than .1 second, and on all three I was able to point out the device's clock start/stop points didn't coincide with actual start/stop locations. Design error.
Fun story that illustrates the pitfalls of assuming your device is perfect and you don't make errors yourself: My favorite year for Mission was in '99; one team had a pendulum with a digital counter. They actually LECTURED me about how I'd better get the correct time because "everyone was off by at least 1/2 second". Well, they "measured" 60.0, I timed them at 59.55 seconds, and my backup had 59.70. Yup, out came the complaints and name-calling, until I had them back things up and, by holding the pendulum between swings, proved that their counter showed 1.0 seconds at 0.5s, 2.0 seconds at 1.5s, etc--- in other words, I was off by 0.05 seconds and they were off by 10 times as much! Precise, yes (off by 0.5 seconds every second), accurate, no (half second is a LOT).
The question that I don't ask irate coaches and kids because it really ticks them off: "If what you claim about accuracy is true, than how come YOU know YOUR time is correct?" Funny how THAT time is always assumed to be right, never has response delay, ad nauseaum.
Last comment about timing: I fortunately have the luxury of being able to pick from the best event help out there, with promises of food, a very nice hotel room, etc. Yes, I had two rookies who were there mostly for training purposes (gotta start them somewhere), but I was lucky in that my LEAST EXPERIENCED crew-member with serious-decision-making authority was none less than our own DARK SABRE, who, I might add, did a bang-up job of running things while I dealt with two annoying arbitrations. No complaints, no timing error allegations, no score sheets to re-do or error-check. Might have something to do with EXPERIENCE LEVEL. He's done this for how many years. . . and you?. . . . .
Ties for first? Sorry, I just don't see an abnormal number of ties this year when compared from year to year. I hear this every year-- "It's so simple, everyone will tie", and the person who tells me this is subsequently never seen on an award stand! Add the variable time done at States, and it gets harder. I've had two tournaments that had ties, two ties apiece, and both had the ties at a lower medal-winning (3rd and 4th, if I recall correctly), and the other in the middle of the pack.
Nationals is a slightly different story, and that's because of the rules, and not due to event super inaccuracy: Look at the tie breakers, and you'll see that the rules assume a non-perfect score. Well, with a perfect score, you WON'T have penalties, WON'T have anything but proper times; heck, they won't even have anything out-of-the-ordinary! Height of the flag would have been a better tie-breaker because every perfect-scoring device WILL have some kind of flag height! But, alas, I can see someone complaining, "They didn't measure our flag right. . . ."
