Ranked points not calculating correctly

Hello! I've noticed that I'm consistently being awarded fewer ranked points than I should be receiving at the end of a match. Maybe this is due to the new "lobby balancing" system, or because I'm a solo player? (please note that I'm in "Even" lobbies with players of similar rank)

In the first video, I extract with 1 silver holotag and 1 credit chip, for a combined total of 5400 RP. I received 4600 RP at the progress report screen, 800 less than expected.
In the second video, I extract with 1 silver holotag and 12 credit chips, for a combined total of 9800 RP. I received 9000 RP at the progress report screen, 800 less than expected.

I've also extracted with 1 silver holotag, worth 5000 RP, and received 4600, 400 less than expected. So it's not always the same amount.

Mind sending a few thousand RP my way as compensation? :P
