Should I believe her?
Why is it important? Jealousy?
Is there any way to verify that claim?

Still new to this but my understanding is that since the provider doesn't have lots of clients in one day she will not need to rush and clock watch in order to be on time with the next client.

NOT! But, thank u anyway

"Unlike her ad, which says that she sees only a couple oof guys a week, she had at least 3 appointments that night, not that this matters a whole hell of a lot, but might be worth noting."  

What is the definition of low volume? Is that 1 client per day, 2 clients per week, or 2 per month?  Without an official definition, it is pretty meaningless.

Exactly! For a provider low volume is a self-defined term, depending on her needs and ability to perform.

There really is no way to verify that claim.  "Low Volume" really has no solid definition.  When I say low volume in my ads what  I mean is I see only one client a day and I don't see someone every day.  This is what I mean.  Others may have a different meaning.

I advertise as low volume and for the exact reasons that you stated.  
I too only see one client a day or sometimes a week. It's just my preference.  
I also like being energetic and really enjoying my clients.

1.  Should you believe her?  
WHO CARES? What is this ridiculous idea that a woman who has sex more often in any given day is somehow less clean, enthusiastic, tight, valuable, or whatever BS some clients are so worried about, than a woman who doesn't?  A good provider, whether she's fucking her brains out from morning til night or if she only sees 2 people in a month, will be fresh and energized for every client.  If she isn't, it probably has more to do with the fact that she isn't very good at her job than the fact that she's seen multiple clients in a day.  

for fun:

One a day, one a week, 5 a day or 5 a week does it matter???

1  No
2  No
3  No

I thought that meant she is not a "screamer"  

I'd give as much credibility to a providers that advertises "low volume" as I would a client who says "he's new to this". Just like a person who claims to be "smart"... People who are any of those things, will most likely not mention it.  

And then he arrives with a dirty ass and bad breath. "Clean" and "low volume" are highly subjective terms that rarely mean the exact same thing to two people

That leaves me out.

I can have 1 client in a day, 3 or 4 clients in a day, and sometimes I'll go 2 or 3 days with no clients at all. I guess I average about 6-8 hours a week "working".

I guess that means we can't believe him either when he insists he never would go with a TS girl?

Holy cow! Maybe I misunderstood the phrase.
You are a genius comrade!

Okay, I will inform you about the results

Correcto-mundo señor.  

I totally love your post. But sort of see the point of the OP. It's obviously a business strategy.

Personally, I can be considered a low volume provider, (meaning I don't see over than 2 to 3 ppl a day (sometimes fewer) now would I advertise that? No because the psychology behind it is the more people rave and rant about someone the more you want to see her. Think of it this way the majority controls the rest meaning.....you could not find me sexy or your type but I can guarantee you if ALL Yours friends start telling you how sexy Roxanne Heart is, and this and that about me I can assure you even if you don't like me you will want to see me because the majority is validating me. Your thoughts will change. At the end of the Roxanne is honest what does it matter how many people she sees....she has sex for a living, enough said.  

Very well put together my answer was from a different perspective but Debbie answered it best. Deb you actually taught me something.  

guess it exists in some form or there wouldn't be words for mavericks and contrarians...

We seem to agree about a LOT of things lately, and this is definitely one of them.

But I've also seen it mean that a provider is simply too busy to see a lot of clients, so saying she's "low volume" explains why it may be hard to get an appointment with her as soon as you'd like.

.... when I'm right

You can never really know if someone truly is a low volume provider - in this type of arrangement its not that transparent. The term itself is very relative, to some it means only one client per day (like my former ATF), and to others it means only 2-3 clients per week. Others still may mean 2-3 per month.

Low volume escorts dont see that many hobbyists.Low volume escorts try to run away business from high volume escorts.escorts need to worry about own business.Instead of worrying about others.Who cares as long as escorts are safe and clean.Bullshit marketing.Play safe folk's

As a provider who takes at most 6 or 7 dates a month (on my good months) I don't even use the "low volume" moniker.  Everyone has a different version of what they consider low volume.  In the end, the volume should not really matter as long as the provider is clean, performance ready and provides a great experience.

Most used that they don't want you to know they are 7 days a week from 9 to 5 or have a flexible schedule. It's to entice the gentlemen thinking he's the only one for the day or maybe the week. Also, considering they travel at any given notice... Its Marketing for providers

I don't have a ton of reviews and am low volume. Maybe 2-4 apt a month. Most of the time it takes 10 appt to yield one review. You do the math. If she's averaging 2-4 reviews a month she is seeing 20-40 clients per month. I have 7 reviews in 2 years and 3 doubles reviews in 2 years.
