I'm not sure how long you were in ROCP, or what years my friends whom I visited fairly regularly there were in it (I'm bad with years)… but I'd be curious if there was a period of overlap. My friends were the second owners of their unit, and by the time I was visiting them there, I experienced no major problems with the elevators, so either I lucked out, or the elevators improved over time as problematic parts were replaced, software improved, etc.
There are so many factors that go into determining how many elevators will be needed for any tower, including how large each cab is, how fast, how reliable, how good the destination dispatch tech is, how many units/bedrooms per floor, how tall (and therefore how much time spent traveling more to get to the higher floors in the first place), etc, that it will take vertical transportation experts to create equations to figure out what an acceptable range of service should be before the City can issue guidelines...
…so I'm just using a round-figured threshold at the moment that's neither particularly well-informed nor, conversely, particularly in dispute. (There are others in the industry that have quoted 1 per 100 suites, and a older ratio was 1 per 90 that I was told about, so I'm just using the easiest to conceptualize number out there until there are better guidelines or formulas to apply...
…but yes, the elevator installations in any project would need to be of an average or better quality to perform at acceptable levels to satisfy any set of guidelines that may be established in the future. We just need to find out what average reliability is, and how all the other factors work together so that those living in high-rises won't be held hostage by the system while living in any building.
