Do your main bearing a favor in the long run and level the bare platter with an accurate level and/or levels.
I use selected bullseye levels that cost all of $2-$3 each.
The levels were hand picked by placing them on a sheet of plate glass which had been leveled with expensive/accurate carpenters levels.
Think I went through 50, or so, to find 3 that looked good.
The local Mom & Pop hardware store let me use their high end levels, plus a sheet of flat glass (been shopping there since the 70's).
I'd guess that measuring even keel with various LP's will give various results.
