Until relatively recently, the recommended ascent rate was 60 feet per minute. A few years ago ascent recommendations were changed to 60 feet per minute at deeper depths, slowing to 30 feet per minute starting at 60 feet. The problem is that anyone with an older computer will have a programmed ascent rate or 60 feet per minute. Your newer computer probably has a newer ascent algorithm with a 30 feet per minute ascent rate and possible deep stops as . A slower ascent rate is never wrong. Most divers tend to ascend to fast. And for a dive to 90 feet, a safety stop should always be observed, the longer the better. There is some evidence that coming up to slow from extreme depths (150-200 feet) may cause actual absorption of nitrogen, but not at the depths you were diving. I agree with the earlier post, the other dives were probably low on and dragging you into their issues. The proper response would have been to get them to slow down, monitor your air closely, and be prepared to share air if necessary.
