Groove out about 1mm of stone at the posterior vibrating line. This cut in the stone will be a raised border of acrylic on the denture. This will define the posterior border of the denture.

Make the depth 1/2mm at the hamular notch. Scrape the stone in your palatal seal area decreasing the depth to zero when approaching the anterior vibrating line. (Avoid scraping any part of the tuberosity.) Theoretically your depth should coincide with half the depth of the tissue.

You needn't worry about a space under your recording base as long as the borders of the final wax-up are sealed.
