There is never a reason for any AG athlete to go anaerobic in the swim. Not at the start, not ever. Some will justify it to get some clear water. The cost of that is immense and affects your race downstream.
But if you are smart, you will line up properly where you belong by pace, you will start your race very controlled and aerobic, never gasping for air and you can line up on a random pair of feet and let that person clear your way for the first 300-400m, go easy.
After that, come around the feet if the pace proves too slow and work it yourself for a bit.
Shortly you will start to see the same cap and pair of arms next to you swim stroke for stroke your pace. That is the person you want to slip down and line up on the feet. That is your pace with 20% less effort. Conserve. You want to sight as often as you need even on the feet as you want to assure that the person can hold direction and is taking you to the right place. Don't just put your head down and be dragged zig- zagging.......
Bridging and sprinting is reserved for PROs. They train that way, they can take it. Far too many AGers have a great swim, sprint, bridge, draft, bridge......have a great bike, way overbike than roll into the run for actual walking. The error actually started with the swim, once you go high aerobic and anaerobic, you burn your matches and you never come down. Those are the race reports where peeps wondered why their HR was so high on the bike and they just held their intended FTP percent power calculated for the race......wrong on many levels.
If you cannot draft, swim your own race. Control the effort that you never gasp for air. Gasping for air at any point is a direct sign you are cooking your swim up. Swim in IM is long enough to ruin your race on a typical AG swim fitness.
Just my 2c. Many will poke holes in what I just wrote here. That is how I race and I am 46, self taught AOS.
I agree with your points save the assertion that you want to find someone your pace and then latch on to them with 20% less effort. Why not find someone 20% faster than you that you can draft with your race pace effort? That way you're swimming at your max, but within yourself and clocking a time beyond your ability. On the other hand, I can see the danger in going out to hard as the OP mentions, and burning matches and not finding good feet. Is there any strategy that splits the difference between those two?
