Thank you dnmilikan and all others who have been kind enough to reply.

I agree with you in that split grade printing gives better prints, not only from under- or overexposed negs.

When saying I let the high contrast exposure time be the determining factor for my low values, do you mean that you use the ”highlights time” also for the dark areas (I have tried this but the other way around, i e the ”dark” time also for the highlights, but altogether it resulted in too much light)?
