I can only answer the QR part, yes your observation is correct. If I recall correctly, QR applies a flat YQ/YR to the first segment then a much smaller incremental YQ/YR for subsequent segments.
Many of us in this board maximize QR segments, so it balances out in the end. It's pretty easy to use them for the long haul intercontinental segments, plus any intra-Europe segments. You'd also most likely use them for any Africa segments.
