John_H, what version of BIAB do you have? The functionality of F5 has been increased every year.

Also, the "Realdrums Tab", by which I assume you mean Opt., Preferences, RealDrums, doesn't factor into this. In the chordsheet - BIAB's main window where you enter chords - click on any bar and press F5. You should see a dialog box where you can set the tempo for that bar (or increase or decrease it by a percentage).
