We can ask Tony to run a Monte Carlo simulation or something. If a chair has 4 seats what percent will have...
4 riders
3
2
1
0*
...so obviously lodging cohabitants will be 1, 2, 3, or 4-person groups. My guess on rules would be...
4-person: always their own chair
3: always their own chair
2: always their own chair except if a single is directly in front of them in which case...
1: half the time the single will feel self-conscious and invite from behind but only if it's a 2-person group
(or always if it's another single -- so maybe better to still have a singles line hmmm)
= what is the overall lift CAPACITY degradation?
* the 0 will depend on the incompetence of the lift crew so for example 0% empty at Mammoth Chair 1 and ~30% empty at Mammoth Chair 2 LOL.
P.S. I like to ride in the middle scooting in last minute, when 4 snowboarders stand together on the "Wait Here" bar but have conspired to take 2 chairs for themselves. I shall refrain during the germs, but it used to be ya got 1 point for the move, 5 points for the middle, and 25 if you're quick enough to get 1st chair instead of 2nd...
