Rear main seal mounted in too deep?

[Bigsi15]

Hi all
before I put my engine in I wanted to run something by you guys. I have a horrible feeling Iv put my rear main seal in too far I seem to remember there's quite a bit of metal on both the engine and crank so could go quite deep but then...

Picture isn't amazing but its a good 5mm recessed

Thoughts?? I don't want to do this twice once its built for the sake of a new seal and another go if its wrong and likely to leak!

thanks guys
