If I drip acclimate I use a constant flow, not a drip. I dump the bag and fish into a five gallon bucket and start a siphon from the display with an air tube. I let it flow completely full flow. This goes faster but is slow and steady. IMO
the true drip method allows the water in the tube and bucket to cool too much. So you may give them an idea of the water to come, but then dump them into a different temp.
