This,in my opinion,is the problem with the Part-15 rules.
We all know the 250uV/meter rule.(or should!)
But how does a hobbiest go about measuring this,to be sure he's compliant? Sure,you can get a Field-strength meter,but it would need to be calibrated,and perhaps even FCC certified.
Certified/Calibrated Field-strength meters are expensive,out of grasp for anyone considered a "hobbiest".. Whats the point of buying a $2K meter for a $100 transmitter anyways?!
So how can "Average Joe-Radio" comply?
It seems it's a Catch-22.
Thus,I say- Run with the 25mw,put up your antenna,use a clear frequency,and clean content. Nobody will be the wiser. Everybody here does it on a daily basis,and so far I think there's only been one or two people that got a letter from the FCC,probably both tipped off for offensive content,etc.
If I were to "get the visit" I'd simply state the above,and ask them if they would help me get everything setup correctly since he's already there,and has a Field-strength meter in hand. Take advantage of the opportunity,and let him know that you're more than willing to comply,if they'll lend a FSM for a few minutes,so that your *able to*.
Obviously if you're *WAY* over the limit (running an amp,etc.) they'll know,and the above plan might not work out as you'd wish.
Your best bet is to comply,and fast -they'll be back in a few more days to check again,if you're still way over the limit,you're screwed! They only give you 3 chances,at the most.
That is,if you even get a warning..If they see power levels that high they'll probably just send the "Cease and Desist" letter. (pull the plug or you're in for it!)
