My guess is that 30 outages at a time and 50 seniors per outage are both very high. I haven't seen a 50 Sr outage in a while.
Figured I'd weigh in, since this is what I do. Average outage crew is approximately 45 Sr. Techs, some take in as little as 25, some still as many as 100. My biggest request this season was around 100, the smallest around 20, remove those from the equation and the rest of the sites average out to about 45 Sr. techs per outage.
As far as how many outages there are per season, the spring normally has anywhere from 30 to 40 (going back to Spring 2014 there were 2 season>40, the rest were 30-34 give or take. The Fall season normally has a lot fewer, averaging around 20, give or take - this season is definitely an anomaly that happens every 5-6 years.
Hope I was able to shed some light on the conversation,
Take it slow,
