I'd love to refute your argument if I could just understand it.
the chairs on a low speed lift come around and pick up four people at the same rate that the slow moving chairs on a detachable lift do. then both lifts have to drop people off at that same rate. the high speed lift moves no more people up the hill. it just make's the time on the lift shorter.
It still sounds to me like you're making the argument I just described. The "time on the lift is shorter" means time between when you plop yer ass down and when your skis hit the ground at the top. If that's shorter, than the only way for the high speed lift NOT to move more people is if you're loading people much more slowly, i.e. the gap between chairs is large.
How about an extreme example to illustrate the point:
Time on lift = difference between when you sit down in the chair and when you exit the chair
Let's suppose both lifts have only a 1 person chair so we can ignore that variable.
This time interval for a slow speed chair equals 10 minutes.
This time interval for a high speed chair equals 1 second.
If there are 10 chairs going up at any given time, then you get 10 people up every 10 minutes.
Assuming there are 10 chairs going up at any given on the high speed lift, then you get 600 people up in 10 minutes.
The only way you'd get the same number is if one person shot up there, and then you didn't put another person in the next chair for another 59 seconds.
But we know the gaps between chairs are essentially the same on high speed vs. old chair.
If this doesn't convince you, try riding each chair with psu96 and I think it will become painfully obvious how much longer the old chairs take. (just joking)
