I'm not 100% sure about the mechanics but my experience because I spent money to try and failed as well... (honestly its a bad habit and adiction at this point)... there is some truth to this speculated theory.

The guide I used was completely in japanese and the guy who made the video could only translate so much... if you boil down into the Fou's, EXP Cards and CE's, it gets a bit more complicated.

But the 3 star servant is a 1% chance pull in the FP gatcha which is why it helps indicates when you are beginning to get lucky and can pull SR or SSR servants, but bare in mind this is not 100% failsafe method because the entire theory is quite complex an there is quite a bit of maths to do if you want to accurately predict your pulls.

Just don't get too high hope and thing you will 100% get your desired servant... like I also failed on Jack when she was rate up but I pulled her later as well as Tamamo, so yeah if you save up and do a few pulls when your rate is high, you could get a servant you want or a decent servant. But if you want to do hardcore raids like Rashomon, then invest time on leveling the correct servants... since Meta is important.
