Sorry, but this recent update is not helpful. This card is testing the Parkland formula, which is 4mL. Other resuscitation calculations use 2mL. If you want to test the adequate fluid required for resuscitation, you are better off making a new card. In reality, adequate resuscitation should be monitored with urine output, so maybe that is a card worth making instead. The American Burn Association guidelines recommend 2–4 mL/kg/%TBSA. Perhaps that is what the change was intended to reflect.
If there is a source that proves me wrong please include it in the card, as there was no source for the previous card change.

See comments. Thanks for the discussion!
4 mL/kg/hour for the first 10 kg
+ 2 mL/kg/hour for the next 10 kg
+ 1 mL/kg/hour for the remaining weight
