No it's not standard for every engine, in the 7.3 there is a ton of factor's that affect EOT, my truck was seeing 260's not towing and it took a while to find the answer.
Yes driving style, condition, mileage,mods, and location all matter.
For example the PCM advances the timing to help raise temps when you fall below a certain value, 180 if I remember correctly, and will advance it even more at 160.
I went through this same dance with my truck and I assure you I have a reasonable amount of knowledge, but suit yourself.
