I wouldn't pay much attention to percentages over time. They're amazing for figuring out where specific videos went wrong and how to improve content but virtually meaningless in terms of overall channel success especially comparing yours to someone else's. Percentages over time are almost always flawed with nearly everything in life as they are too easily effected. That's the main reason companies always use percentages rather than whole numbers to give facts because they can always be analyzed different to appear better.
People will argue it but it's just how it is especially on YouTube. If you upload short content - under 10 mins, which is basically the standard now a days, then you should definitely have a crazy high retention percentage or else that means 50% of a 5 min video is a measly 2.5 mins and probably an indicator of some sub par content. Yet you can upload a single lengthy video, get half the views and a third of the retention and completely blow that shorter video out of the water in rankings. On the other hand people can absolutely love a longer video but if they unfortunately can't watch the full thing at once then you're percentage is going to plummet. Keep percentages to yourself for your own data, that's the only time it's useful as no one uploads the same exact content therefor comparing % is pointless.
If it helps you at all my 90 day is 67%. But I'm willing to bet your channel is growing way faster due to your channel type. My retention % and overall watch time is probably a lot higher despite overall views and subs but that's merely because I upload longer videos. Not because anyone's content is better or worse. Comparing channels is pointless in that sense.The percentages are pretty much just a ego kind of thing when comparing. Just keep doing what your doing because it is clearly working and people are liking it! Congrats on 1k subs btw!!
