the idea is to increase resistance downstream of aorta, to bring more blood to the lungs and get it oxygenated

Squatting would lead to compression of femoral arteries and increase in peripheral vascular resistance. This would back up to the heart and increase in LV afterloadand pressure and because of that - the intensity of MVP.

I do not know what "other" resources you are using, but turns out that FA is right

imo, squatting will increase the MVP but will lessen the murmur (more blood, so hard to hear it). does this by increasing TPR and therefore afterload on LV.

valsalva will increase the murmur (mid-systolic click) as there is less blood so its easier to hear the click. not sure if valsalva would effect the MVP itself though, i wouldn't think so.

Difference is where the click is best heard. In decreased preload, (valsalva) is closer to S1 and increased preload (sqatting) closer to S2.
