That's actually incorrect because of drift (if D's clock is faster than A's clock, if you don't correct for drift the measurements can't be reliably compared).

That's actually incorrect because of drift (if D's clock is faster than A's clock, if you don't correct for drift the measurements can't be reliably compared). You'd have to correct for drift for every step (A->B, B->C, C->D) before you start.
- Strilanc 14y agoRight, I was assuming negligible clock drift between when each measurement was performed.
