OK Daz,
You should have asked Paul for a printout of the "before and after" settings, he normally does supply this, I dont know why he didn't offer you a copy.
If you make any changes, try to kep the adjustments recorded. Put a chalk line on the rods so you can count the turns, that way you can get back to Pauls settings. Make sure you do both sides identically to keep symetry.
