BTW, formation flying is the most obvious way to overcome the 1 d.p. limitations of the cockpit instruments, at least to some degree...

That was my idea too...
Yesterday I did pressure and temperature measurements. And got some conclusions that must be cross-checked.
Pressure measuring method:
1. Place a Ju-88 in a beach (Sea Level).
2. Set altimeter to 0.
3. Read pressure in milibars directly from the Kollsman window, in the upper side of the german altimeter.
Temperature measuring method:
1. Place a Ju-88 where you want to test the plane.
2. Read outisde temperature indicator
Facts found:
A) I get different values of pressure and temperature in the same place every time I reload the mission. Sometimes they'll repeat, but they tend to change more when a different plane is loaded in the same place. --->
Temperature and pressure are not always the same, there's some grade of randomisation. (This must be confirmed).
B) Ambient temperature is different from water and oil temperature before starting engine.
Clues to test:
-There's the possibility to switch from the cockpit of one plane to another, at least altimeters can be cross cheched in that way; same mission load, planes placed together on a beach, check if all altimeters have the same pressure reading in Kollsman when altimeter set to 0. --> If same readings oK, reload the mission to test randomisation of parameters.
