No expert Eric - will do my best however more experienced/knowledgeable people will hopefully answer.
I assume with this type of propeller, you can not change the ground adjusted pitch angles in flight i.e. you likly have three preset positions that are relative to the one on ground adjustment.
My suggestions;
Select the In Flight Adjustable (IFA) take-off (TO) adjust pitch for a static (aircraft tied down securely) rpm for 5200 rpm
Go fly the aircraft and see what the TO rpm rises to during ground role & initial climb (500ft) at your normal climb out air speed & attitude You will likly find it goes to 5700 - 5800 rpm. If so, you have now got Max power for TO (Max 5 minutes).
Now check your Climb rpm - should be no more than 5500 rpm (aircraft attitude/airspeed sensitive). Reduce power if so desired.
On achieving your planned altitude, switch to Cruise. The rpm should drop to somewhere between 4800 - 5400 rpm (Max 5500 rpm)
As you only have inflight control over the above preset positions AND your throttle (power) you can now adjust throttle to reflect an appropriate engine speed for your planned mission.
Should you find that the MAP readings (in Cruise) are not what you would expect, you can then adjust the prop (course/fine), on the ground, in small increments, in the direction you think will increase/decrease MAP.
NOTE:
MAP is relative to pressure altitude. The only time your MAP indication will be as per Rotax charts/tables, is when your engine is operating at the same pressure altitude (Standard) as the Rotax derived results/recommendations.
The two charts you have referenced; The table seems to be for operating on 95 RON. The graph gives MAP for both 95 & 98 RON
If fitted, you can use a fuel flow gauge to set an appropriate engine speed.
