Looking at the patch and the CVS history I'm getting the impression
the the change which introduced it (tcp_input.crev.1.16) was an attempt
to change the representation of srtt so that it keeps 5 bits after
the point, thus increasing precision. It was just not communicated
correctly, and likely incomplete.
But if done correctly, it shouldn't have bad effects.

best regards
Matthias
