Our new style approach plates came out under a system which used a different 'rounding' to the Green Pages, so figures differed by 5ft. All figures are to JAR OPS standard, but we've chosen to round to 10ft, not 5ft as we did before. The problem is now sorted, but it'll take a little time before all 'old' pages are amended. If a difference exists then use the Green Page figures as they are rounded to 10 ft which we'll be showing from now on. The Green Pages will stay as they show ALL minima to all possible approaches at an airfield, whereas the approach plates show minima only relevant to that approach. The vertical profile, as you say, is a combined ILS & LLZ; the aim being no page turning in event of G/S failure, unless the LLZ profile is very different, in which case there is a separate chart.
RDH - height of G/S above threshold, ( ie the antenna) not necessarily the lowest part of the a/c.
