I think the best idea for a change to pop would be to make it so we can use 100% as we have always been doing but make it so we can research the ability to put more % into each so:

Miners 25% research to -> 30% or 35%
Researchers 50% research to -> 55% or 60%
Construction Workers 35% research to -> 40% or 45%
Shipwrights 60% research to -> 65% or 70%
Security Guards 50% research to -> 55% or 50%

Obviously you can mix and match the numbers and figure out where each should be in the research line
