Can someone explain this map please?

Hi all,
The name of the map is: 7A1C2 RPC limit. map, max. gradient for setpoint CR pressure steps

I am not sure if I understand the meaning of this map. Maybe it is just a language problem.

x-axis is mg/Stroke
y-axis is RPM
Mapdata is railressure

I am speacially confused by the low pressures between 750 rpm and 2500 rpm.

I inserted my other rail maps too. I didn't insert the different SVBL.

I am sorry for this question. Maybe it is really stupid.

This is a gradient control map, It tries to enforce some short of smoothness to your rail pressure behaviour. For example if you move from 55 to 65mg stroke at 2200rpm then you should not have an increase of higher than an X value from one cell to the other.
I would say as a rule of thumb try to keep within 250bar gradient for 10mg/stroke increments and every 100 rpm increment in order to get your engine to run nicely and avoid excessive strain on the fuel system.
