So as I wrote in my introduction I started to actively using active focus and be conscious about my eyes at the start of march. My -3.5 normalized was pretty blurry then, about 20/40 in indoor lights (though I was using them for years, again, see introduction). In the middle of March I measured 20/20 on snellen in indoor lights with them! I switched to -2.25 differential, waited 4 weeks. At that point I had almost no blur challenge nor indoor or outdoor.
So I got the new normalized in the middle of April as a -3.25. I could read 20/50 on snellen with indoor lights. I will be honest the first few days and the first week was pretty disheartening. Blur every and even with af I could just make it a bit less blurry and not clear. But I said to myself that it’s normal and be happy to have blur challenge. After 1 week it got much better and today (May 1) I measured 20/20 with both eyes on Snellen (20/25 and 20/30 on separate eyes)! It was indoor but strong sunlight, so I would not necessarily consider it as true 20/20 but I’m pretty happy with it. So the current plan is to order a new differential (-2.00) which takes 2-3 weeks to ship from Zenni, so hopefully I will be able to change to them as soon as they arrive.
tl;dr:
March 1: -3.5 -> 20/50
March 18: -3.5 -> 20/20
April 20: -3.25 -> 20/50
May 1: -3.25 -> 20/20
