Just because a large amount of applicants use this forum and the spreadsheet, doesn't mean everyone does. There are also a lot of other communities (Like facebook groups) dedicated to this same topic. Some people might participate in those communities and not this one. Meaning they don't know about the spreadsheet and they don't use it. We only see 60 or so apps submitted in April inland according to the spreadsheet but IRCC might have received a 100 apps last month and 40 people just don't use the spreadsheet. Just because you only see 1 AOR update, does not mean that only 1 AOR was sent out today.
I'm sure they didn't mean everyone, they're just talking about our particular spreadsheet. Even accounting for the fact that only a select few use the spreadsheet, it's true that it moved faster earlier in the month - some people were even getting their OWP's approved the day after receiving their AOR for PR. Can't fault people for being eager!
