This is a super unserious hypothetical topic, but I'm interested in hearing your thoughts. What would you think if you came across a provider who had proportional rates as opposed to the usual built-in discounts for multi-hours that most providers have?  

I would book the one with discounts, and not book the one with proportional rates ( meaning each hour is the same price)
The first hour is to get set up.  The next hours is just her being there.

Tbh I feel my overnight rate has a very reasonable considering I see many who are twice as much.  

I am the same way! I rather get a FMTY & overnight so my rates reflect that!

Your example comes across as if you’re asking if we want to pay more or pay less. The answer is too obvious. So I think maybe that’s not exactly what you meant?

...would be practical and make a lot of sense.   If I were a provider,  I'd definitely be trying to book multi hour appointments and set my price to motivate the guys to take advantage of a perceived deal.  i would assume that there is inherent risk in every appointment, travel, preparation, down time etc...   I'd bet if a person penciled it out, they'd still be money ahead if they ran a second hour at 25% off.  Obviously, if her incall has a turnstile instead of a door then no, it wouldn't pencil out.  

Doesn't mean I wouldn't see her, but I'm far less inclined to book a long engagement.

Exactly. I prefer longer dates for sure I just don't feel you can truly get to know each other in an hour or so. I FMTY, Overnights and even lunch / dinner dates [4-6 hours] is perfect too.

Im in agreement, this makes no sense.  

how some gal's rates go up on a per hour basis the more time you spend with them.

Seems like they're discouraging longer dates although they're willing to do them.
