Keep in mind a 3 way splitter has two 3.5db and one 7 db out.

Wrong. A splitter reduces the output by -3dB which is half the power.
The extra -0.5dB loss is from losses in the bifilar wound xformer. If
two of the ports each have half the input power, there's nothing in
the budget left for the 3rd port.


Part of the extra .5 dB loss is in the cast aluminum 'F' connectors.
I ran Q. A. I ran tests on hundreds of samples to qualify them for our
MSO to purchase the best quality we could find. We bought splitters by
the thousands, and coax by the pallet

Also, eight way splitters are listed at -10 dB, not 10.5.
