Comparing the same head on different benches gives you no additional information
You have to compare different heads on the same bench and adjust for conditions.
One thing about velocity is when the intake valve is closing you want to maintain as much flow as possible for as long as possible.
Here low lift flow and velocity is important
Many hold the intake open too far for too long then slam it down
They stall the flow
just saying
