Default Cosworth oil pressure question - with a twist

Hi there

Can someone help me out with a question regarding oil pressure on my 4wd Cosworth - have not found anything using search function.

My concern is that I might have too low pressure when lifting of throttle.

Cold the pressure is about 70 psi,
when hot and 2000 rpm it is 35 psi.
so just fine I would assume?

When hot at idle it is about 24 psi, so almost at specification

But what worries me is that when driving along and then lifting throttle and depressing clutch, the pressure drops to about 17-18 psi for a second and then rises to 24 psi.

now should I worry about this?
I am using Mobil1 5w/50

any input would be highly appreciated
