I don't mean to be rude, I am not a good swimmer myself and am very thankful when a race allows for a wetsuit swim. However by definition a wetsuit is "A tight-fitting permeable suit worn in cold water, as by skin divers, to retain body heat"
It is not a swim aid. I understand your argument that the USAT rules state that a wetsuit maybe be worn between temps of 78 - 84 and you are upset that the RD didn't seem to have a plan in place for those temps and that option. I think the RD was correct not to allow wetsuits at all. Anyone who wore a wetsuit for that swim would have exited the swim dehydrated and with core temps much too high to continue in a race where effective temps topped 100 degrees.
If you were DQ'd because your swim was too slow then I would suggest spending some time working on your swim instead of posting complaints on slowtwitch.
It is triathlon and that implies an ability to meet cutoffs in three events without any assistance. If you were a weak cyclist and it was a windy day would you suggest allowances should be made or the cutoff extended for that circumstance?
So you say the RD is correct in not following the rules he posted? Post a no-wetsuits-over-78 rule and people like me won't register. Post a wetsuits-OK-but-no-awards-between-78-and-84 rule and we will be upset at the waste of $255+ when the rule is changed at the last minute. The issue here is not whether wetsuits should be allowed or not or whether weak swimmers should be allowed or not, it is about sticking to what you told people to expect.
If the wetsuit option had been allowed, I'm sure that most people would have elected to not wear one. I would have worn one, and I wouldn't have overheated. As I mentioned before, I've done longer swims in warmer water and felt fine. But that may just because my scrawny arms don't generate a lot of heat and my weak kick means my legs don't get a chance to.
Let me turn this around on the weak cyclists. Suppose there's a nice flat route that crosses one major ridge four times on an semi-circular out-and-back course. There are three roads across the ridge: roads A and B cross at very low passes (say 250' elevation gain); road C crosses right over the ridgeline with a 2500' elevation gain each way. Road A is the planned route for the course, but there's road construction on it. The RD thinks that the construction will be over and up to race day tells everyone that, even though there's good evidence that it might not be. One hour before the race the RD announces a course change -- onto road C, even though with minimal planning road B could have been used instead. Dozens of people are DQed or DNFed because they were not prepared for the climbs. Many others are unhappy because they brought their tri bikes when they'd have brought their road bikes if they knew there might be a lot of climbing. Do you think they would have the right to be upset or would you just say "learn to climb"?
My bike example isn't even as bad as the wetsuit situation because no new rules are being made up on the spot, but the rest of it is similar: the RD should have known there might be a change, he should have let everyone know there might have been a change, and he should have been prepared to keep the impact on participants minimal in the event of a change.
Here's the simple, on-the-spot solution for Eagleman: have everyone w/o wetsuits enter the water 6 min before their swim wave goes off. Pause, note the time, run a dummy chip across the timing mat, or something. Then 3 min before the wave start have everyone in a wetsuit go over the mat. Post-processing the data in Excel would take 10 minutes, tops.
