Stethoscope MVP murmur

Why the murmur of MVP increase with decreased preload and why does it move closer to S1? while with increased venous return it decreases in intensity and moves closer to S2?

can you explain?

decreased preload causes more laxity on the chordae tendineae...

This allows the mitral valve to prolapse earlier in systole, leading to early regurgitation, and a longer murmur.
