Vastly lower.
For most spas (there have only been a few exceptions), hitting 20 sessions in a day is a landmark day. Most men do come all at once, with major busy times around lunch and then again between 2-4am and then there are many long lagging hours that are dead. The problem with everyone hitting at the same time is that not everyone can get seen, leaving some men to walk during busy times. And walking is common, many men will stop by just to see who is working and never stay. So even if 100 pop by, only a fraction actually stay.
Most spas only have a small number of girls on staff, so if those inflated numbers were really true, then those girls would be literally rode to death, day in and day out, all day long, and that is not reality. Many girls sit for hours at a time. Many girls have their fair share of zero dollar days just like everyone else in the industry.
I believe Lincoln.F.Stern is spot on in his assessment that they used a sample section of busier spas in order to inflate numbers and be able to create a report based on sensationalism. I think they also accounted for traffic that probably entered the strip center with no intention of entering or staying in the spa.
I see so much sensationalism used in local news reporting here in the Houston area when it comes to this industry. They are full of shit.
It's kinda like when they report a drug dealer is busted with a certain amount valued at a certain street worth, but in reality those numbers are unrealistic and are only inflated for sensationalism and to help secure a bust.
