A few MPR calculations someone probably did better (in General)

Was curious how much MPR was worth in terms of stats. So I started training my minions 500k stats at a time.

Started at 2,493,821 MPR.
Trained 500k AMF on Tatsumaki, MPR went up to 2,577,775. (83,954 MPR gained)
Trained 500k HP on Saitama, and MPR went to 2,661,051, (83,276 MPR gained)
Trained 500k AMF on Tatsumaki, MPR went up to 2,743,680 (82,629 MPR gained)
Trained 500k HP on Saitama, and MPR went up to 2,825,692 (82,012 MPR gained)
Trained 500k AMF on Tatsumaki, MPR went up to 2,907,113 (81,421 MPR gained)
Trained 500k ST on Saitama, and MPR went up to 2,987,968 (80,855 MPR gained)

Was gonna split the last one between ST and UC, but when I put a few hundred k into ST, I got to 1,999,999 ST, then training One put me to 2,000,001so I decided to go for 2.5m and it did the same thing (damn 64% ST bonus not playing nicely with round numbers). Didn't have time for another cycle before XP time tomorrow (I like recording my progress before and after Saturday XP time), and I kinda wanted to hit 3m MPR so I'm training my XP as I get it until after XP time tomorrow, then will probably record more chunks like this next week.

restarted at 3,505,138 MPR

Trained 500k AMF on Tatsumaki, MPR went up to 3,582,354 (77,216 MPR gained)
Trained 500k UC on Saitama, and MPR went up to 3,659,155 (76,801 MPR gained)
Trained 500k AMF on Tatsumaki, MPR went up to 3,735,556 (76,401 MPR gained)
Trained 500k into AMF and UC*, MPR went up to 3,887,202 (151,646 MPR gained**)
Trained 500k UC on Saitama, and MPR went up to 3,962,471 (75,269 MPR gained)
Trained 500k total UC/AMF***, and MPR went up to 4,037,384 (74, 913 MPR gained)

*I guess I forgot to record the in between
** (Guessing 76,010 gained from whichever i trained first, and 75,636 gained from the second set based on the pattern
***100k UC, 400k AMF
