There is a bit of a trick, but there are ways to make it easier. This is why in the tweetstorm I said the various parts of critical chain have to be used together, like forces balancing a building. In order to use median (most likely) time estimates and late starts, you also must use buffers. Instead of putting a little bit of safety margin at every little step, which explodes the lead time of the project w/out actually reducing risk (since delays are passed on and early finishes are wasted, as the table-building ex above explains), w/ buffers you pool all the safety margin together, where it can be used by whoever actually needs it. This works better because Murphy always strikes one part of the project disproportionately, not every step equally.
