The higher KV coil has the capability of higher KV if and when it may be needed. With all the stars in the universe aligned at idle no load KV will be steady under any other conditions KV rises and falls as the air and fuel mixture change.
The higher KV coil has its advantages but I doubt folks would ever know it when it did its thang other than on a cold start with a cold engine cold fuel cold air low battery supply and cylinder pressure.

When you accelerate the KV will spike high if it did not the engine will fall on its face like a bad accelerator pump. A standard coil is normally all that's needed it will in cress with demand enoufh under most conditions.

When you get time look up "snap throttle test places more demand on the secondary ignition"
