Gotta be careful about tweaking:
1) If you want to be recognized for being able to send slower or faster than 15 wpm, this can be accomplished by the current system of buying those little colored stickers indicating your preferred WPM from the ARRL then attaching them to your Latest ARRL University whatever diploma.
2) Already to many confusing meaningless designators.
3) If the examinee can't figure out where he is presently located and can't look out the window to see if the Grey line is nearing where he is at, then he's got bigger problems than getting a hobby license.
4) The correct answere (a) should be easy to memorize especially since he's sitting for the REAL HAM license.
Lighten up friend, nothing not to get or get over, just a bunch of guys (and Tisha) on an obscure hobby forum having a little fun while waiting to celebrate New Years Eve at which time we can fire up our rigs and really create some SKN confusion.
