In my car I have this behavior:
Drive at 30 mph
Enable Cruise Control
Lift Cruise Lever all the way up to increase speed by 5mph
Speed increases by zero or one mph
Lift Cruise Lever all the way up to increase speed by 5mph again
Speed increases by five mph (and is OK from here on in
So... lifting the lever all the way up or down to adjust speed by 5mph works, UNLESS it is the first time you've done it after setting cruise control in which case it seems to do (almost) nothing.
Can someone else try and see if this is unique to my car, or a 'feature'.
