The new distribution is better because it is far more uniform, which is
the entire purpose. The proposed rule is extremely simple. The email
exchange was about how to implement the formula in a computationally
efficient algorithm without going through a lookup table. That is
something quite different. I would say that the current LRM algorithm is
highly non-intuitive and therefore misleading and unexpected. Also not
what users would want.

	It is unclear how the new distribution is any better. As I wrote
earlier, "the rule needs to be unambiguous, but it must also be simple
enough for users to figure out what happened." Coverage reports must be
actionable, that is, users need to be able to easily determine how to
cover certain bins, and this proposal complicates that determination.

	I believe that simplicity trounces the need for uniformity. As
proof of how complex the new rules are, I submit the email exchange
between Steven Sharp and Shalom - it took these two experts several
iterations to arrive at a correct formula. Are we seriously suggesting
users must do this computation in their heads? The current rule is
simplistic but predictable.
