Test whether a wedge covers the missing range
The speaker explains that he tested whether the new wedge could comfortably cover 130 to 140 yards between his pitching-wedge and gap-wedge ranges. In his test, a full swing produced 140 yards and a roughly 90-percent swing produced 130, leaving 135 accessible between them.
