The pay table for Double Bonus commonly found is

had a progressive attatched to it at $1500 for quarters would it be
positive, and how about at $1800 for the Royal if it reached that
high? It doesnt matter how much detail is provided in the answer but
I would like to see as much as possible...
Hey, stu -- Got your eyes on a juicy one, eh? 
staninv provided an ER for a $1500 quarter meter assuming an optimized
strategy (100.13%). I'll add a bit to that (be careful in what you
wish for, with that "as much as possible").

It should be evident that the various tutors (winpoker, frugal, vp for
winners, etc.) will provide info on ER's. I know you're familar with
winpoker.
stan's reply likely came from one of the above. I'll note that tutors
provide an ER that assumes you make strategy adjustments to take
maximum advantage of a progressive meter advance. At some point, 2
card and 3 card RF holds become favored over holds that otherwise
would take precedence.
The casual player who tackles a progressive may not prepare in advance
and simply stick to a standard 4000 cr meter strategy. It's worth
noting the ER in that case (and the "on the fly" calculation).
As you note, a "standard" 9/7 DB paytable returns 99.11% with
optimized strategy. Any of the tutors noted above indicate that 1.67%
of the return is contributed by the royal. If you boost the RF payout
by 50% (to 6000 coins), the RF return is increases pro rata when there
are no strategy adjustments. Adding .83% to 99.11%, the progressive
return becomes 99.94%.
------
I have no problem with a casual player taking a stab at a progressive
in that fashion (count me in there on occasion). In fact, a haphazard
attempt to make a few strategy adjustments may do more harm than good
if a little ill-conceived.
However, the opportunity to add .2% to play with just a little advance
preparation isn't a bad idea -- particularly if you reguarly watch the
meter on a play for a repeat run when attractive.
I'll also note that milking a little extra return isn't a bad idea
with a progressive. Say that you shift play away from NSUD to 9/7 DB
with a $1500 meter, given the higher ER (whether you adjust strategy
or not). You dependence upon the royal for return increases from
1.8% to at least 2.5%. That's a 40% stronger drain that you must
support between royals and looking for incremental return as
compensation for the risk is well-advised.
------
Strategy adjustments advised for a progressive again can be found in a
tutor such as Frugal VP or VP for Winners (I'm not advocating one over
the other here, just listing in order of release).
For a 6000 coin meter, most of the strategy changes are of no surprise
-- e.g. holding suited AT becomes palatable, suited QT is favored over
unsuited QJ. 3 card royals are hold over J-K high pairs or 2 pair;
3RF without both an A and T are favored over bullets. There are other
changes.
Perhaps the best way to prepare for a given progressive game is to
decide on a meter at which you'd play it and then note the relevent
strategy changes. Then, advance the meter by another 25% or 50% over
reset and have another set of adjustments in your hip pocket for the
exceptional climb.
