Sure, but it's fair to say that if someone has 75% availability and must miss meetings because of external events, their output is affected.

Besides, I am talking about a drop in output for a given employee, so the comparison to other employees is pointless. If my productivity dropped by 25%, I'd hear about it pretty quickly, and I doubt my explanation would matter much in my performance review.

Your company must have some good metrics or they are measuring clicks per minute if you think they would notice 25% output growth very quickly. Likely you just wouldn’t get promoted and that might happen to your coworkers in due time

You are getting hung up on arbitrary numbers in a fictitious example
