I didn't find an official rule anyplace, but the amount entered by a reviewer is supposed to be the total amount rendered EXCEPT for the optional tip. ("Obligatory tip" for a service upgrade is part of the fee amount entered, e.g., $400 GFE, $500 PSE. The optional tip is what you decide to add before leaving, just like you tip your barber depending on your satisfaction with the service. Some guys mention that in their review but do not add it to the fee amount.)
For the vast majority of TER listed Providers that I can think of, their rates are almost always pretty clear on their ads or websites. It is pretty much at the lower end and some of the former "backpage girls" that tend to be upsellers. If there is an upsell, it is almost always made clear in the written review, often even the General section.
The appearance of "upsell" can vary with client, too. A guy who has read reviews and her website will show up informed and with the proper amount in the envelope. A less well informed client who has not done his homework might THINK she is an upseller when she is not. (There were even some recent posts from guys asking about that.)
There's yet another consideration: the TER Profile is not the definitive place to look for fees. Her ads, P411, website or twitter is where she will keep her info more up to date.
I think that adding a new field or fields to salami slice the fee would add to the clutter and make it more difficult for guys to submit a review.
Sorry. Just my 1 cent + 1 cent upsell for extra paragraphs = 2 cents.

Just curious, if on the review under coast of service, if there could be a place to choose if you paid a flat rate or if she charged for extras. Some people pay a flat rate, and get different experiences that others. Which is fine. Some reviews are good at mentioning if there is an upsell, but some aren't. I don't know about anyone else, but I'd like to know if the provider charges a flat right, because sometimes their ads don't say so. Nothing against charging for extras. It's just good to know going in.
