Shift out speed mph

What mph are you guys machine shifting out at with 26 " tires? I understand it’ll be different for everyone but trying to see where others are at.
I’m trying to dial in my dalton kit on a new team primary and didn’t get very far. It seemed like at 58-5900 rpms it slowed down but there wasnt a real pause on the tach it just slowed down a lil and was easier to read. I was hitting about 50 mph and running out of room. Wondering if I wasn’t in it long enough and was almost there, I got upto 6150 but it was a slow pull and I figured it shifter out way before then.
I started with the alum tip weights pressed in and 3 long screws and it seemed to be around 5750 and round after round i ended up removing all the screws and drilled out the tip weights I still only seemed to be around 5900 so I was thinking I’m not seeing the shift out. Also didn’t seem to feel.much difference between all the weights maybe from 5700 to 5900.
I don’t think it’s because of my mods because I don’t think a bb kit and muffler is anything radical just wondering what I’m missing.

I’m gonna call Todd tomorrow for some help bit looking for more here as well.
