I only have a few little things to say in this, since most of this is known...

First, while the table mechanics are well known, the actual process is dynamic. Depends on party make up, positioning, gear, party tactics (all DPS on one mob vs. multi-kill). You need to be flexible as a tank and deal with the situation as it changes.

Second, if your tank loses aggro on a mob, don't go wacko and run all over the map while still attacking said mob. Bring it to the tank and stop attacking it until the tank regains control, you're not being helpful otherwise.

Lastly, provoke only puts you at the top of your party's enmity table, not the table in general. So for any time I hear someone say, "I was doing (some open world content) and a tank came up, provoked it off me and reset it!" All I have to say is...
