Ilford processing times (Pan F)

After my recent success with TMX, I delved into my freezerful of film
and pulled out a roll of Pan F I want to shoot. But I'm a bit mystified
by the enclosed processing instructions.

Was thinking of using D-76, and they have times for both this and ID-11
(same times, since the same developer, except that they list ID-11 at
1+1 but not D-76, though I assume I can also dilute it). But they show
the same times for both ISO 25 and 50 exposure. Can this be correct?
Other developers show different times for the two speeds.

They also show times for Perceptol, but not Microdol-X. Richard K., you
said these developers were equivalent: would you use the same times for
both of these? The Humumgous Massive Really Really Big Dev Chart
(http://www.digitaltruth.com/devchart.php) shows different times for
these (9 min. for Perceptol vs 12 min. for Microdol; should I just use
their recommendations?
