It's not as simple as '6x can get 1y into orbit, therefore 600x can get 100y into orbit'. I think it's just that the biggest hurdle of getting something into orbit is actually getting it out of (most of) the atmosphere at a decent rate. Once you're there you can take your sweet time gravity turning into a circular orbit with weak engines and no fuel. The design I used could probably be made more efficient by reducing the number of LFTs on each 'booster' stack, thereby providing more T/W at launch and less dead weight once you're up in the air.

I just got this: Yawmaster + CP + 3xLFT + 1xLFE + Decoupler Into a 70km circular orbit with enough fuel to spare for a deorbit burn with this: Tricoupler + 3x((6xLFT + 1xLFE) + 3x(Radial Decoupler + SRB + SAS + 5xLFT + 1xLFE)) + struts ...and I didn't use vertical snapping MECO: Apokee: And a nice, 'soft', touchdown (which apparently scared the pants off Jeb).

I did it with 0. Just before landing: Touched down. It was a bit wobbly but the 11 SASes kept it under control. And yes, it does stand up with SAS turned off. Nothing broken, but it looks like some of it came apart :/
