133219-diminishing-returns-applies-to-rating-or-flat-percent-or-both

So, I'm trying to determine the validity of this concept I'm hearing that only rating suffers from diminishing returns, not flat percentage increases. So, the critical hit rating that hit over 30% would have DR, but that if you reached that with rating, then gain the esper 8% crit buff, or the medic 6% buff, you would get that extra 14% over 30, and it wouldn't diminish. 
 
DPS meters are showing several espers that are hitting a consistent 42-44% crit on all of their skills with 30% rating, then the extra 14% from esper empower and medic buff. Wouldn't their crit be a good deal lower if DR hit the flat percentages too? Someone who knows math and how and why help me!
