Bedmesh not to bad, but first layer not good

This is my bed mesh. I would say < 0.3 mm is a very good bed. At the moment I am printing ABS and the bed is fired to 100 °C. How long do you wait until starting the print? because I worry about that the printer needs some time to stabilize the bed expansion process. - otherwise the bed will come up and the first layer gets to much pressure. That is exactly what I see. If I print maybe 6 parts on the platform after probing the mesh the first 1-2 parts have a perfect first layer. The do not need to be aligned in the middle of the bed. But after maybe 10 minutes the bed has expanded more an the layer of the following parts is to much pressed. I need to lift the nozzle manualle about 0.05 - 0.08 mm. That the layer is perfect again.

So I think my bed expansion process is not finished before the print starts. So my question is: how long do you wait until you start printsing?
