Not in favor. Any change from first and first out based on the current
minimum allocation unit is a mid game change which is patently unfair.
Automatically changing the allocation size is quite different than
requiring a policy proposal _based on current conditions_.
Circumstances may chance the popularity of such a proposal. One could
argue that it too could be changed. Why not simply change the
allocation unit from meet to meet?>
