Given Brayd's & Davey's horrific ending, should combatants contesting 10/12 rounds be weighed 7 days before the fight, 24 hours before (official weigh-in) and also on the night of the fight, which would give pre fight/ringside doctor an indication what he/she might have to face during the fight.
At times I suspect severe dehydration to make weight, but it ain't 100% come punch time. Whilst overall body fluid can be replenished within reason (male 50% & female 60) within 24 hrs, it doesn't necessarily replenish fluid (cushioning) between brain and scull, whereupon few punches making the the head swing can cause brain bleeding.

I am not sure if it would make a difference but certainly the reasoning you have suggested seems sound. There will of course always be the occasional tragedy regardless but certainly something does have to be done about weigh-ins. I think the Zerafa fight shows how ludicrous it can be if one fighter is very good and well practised at weight draining.
I would be most interested in a medicos opinion on what you stated. The notion that if you are dehydrated and have a drink then everything is peachy is just false. The difference between intra and extra cellular fluids and the significant difference between how rapidly those different pockets of fluid replace via rehydration is huge.
