Measuring the length of a “stack” of bricks will basically cancel out any error. Scott A (1) I say “tends (...) (20 years ago, 5-Jul-04, to lugnet.lego, lugnet.color, lugnet.general, FTX)

The randomness of the distribution depends how many machines (...) (20 years ago, 5-Jul-04, to lugnet.lego, lugnet.color, lugnet.general, FTX)

| (...) Agreed, with a large enough sample size. I hardly think 10 bricks (or even 40) would be enough to cancel out all such errors. Besides, if my stacks reduced the error, doesn't that mean the older bricks are actually likely to have worse (...) (20 years ago, 6-Jul-04, to lugnet.lego, lugnet.color, lugnet.general, FTX)
