I do not disagree with the basic PA requirements, for the base stats needed for the common builds
Monk Psi 115 for T4 PA APU/PPU(+15 from max)
Tank Str 115 for T4 PA HC/MC
Spy Dex 115 for T4 PA RC/PC

But the other variants seem far to extreme for their T4 armors. Such as the HC PE
T4 PA req is 90. So with sub par implants.. such as not being able to use MC5 chips I need to come up with a total of +30, I think this is the best logical set of implants I can use.

13 Enhanced Physics CPU V0.1 STR:13*** STR:+2.24
24 Enhanced Physics CPU V0.2 STR:24*** STR:+3.84
32 Enhanced Physics CPU V0.3 STR:32*** STR:+5.12
66 Synapse Soldier MOD S-13 STR:66*** STR:+2.51
72 Hardenbackbone V3.0 STR:72*** STR:+2.70

So without drugs if I did the math right, I can get 16.41 Putting me at 76.41

I point out as above. For a RC Spy, their first PA starts at 80, even though their max is at Dex 100.
80% of their natural stat max
100%
110% (+10)
115% (+15)

Couldn't a similar system be used for classes that have off weapon Power armors?
48 Str
60
66
69(70) something like that? Does that really sound that terrible? Same would go for Dex Tanks I would think...
