I think a lot depends on where you are ?? I am sure at Dublin main they will not be very happy if you drag in at 75 kts from 6+ miles out
If they have asked for minimum speed then they SHOULD be happy - they have asked and know what type you are so should have an idea what speed you would normally fly, normally somewhere like DUB they will more likely ask a light a/c to keep its speed up, but generally if asked for min speed it means min safe speed using available lift devices, so if you are in a larger aircraft you normally do 180 reducing to 160 and final approach speed inside 4, you instead reduce to approach speed and fly that from when you are asked. Even in a light ac if asked the same applies, you might not know the reason, but if you do not comply don't moan when told to go around!
