Okay, round 2.....
View attachment 787746This result going between 5 and 7 leads me to a conclusin And
Grampa brag. 
Doing a remodel of a clothing store as a temp carpenter, with a 5 or 6 man crew. We needed to use gray caulk around the mirrors in the dressing rooms, so tags couldn't be hidden there by shoplifting person. The wall was white. So the supervisor says, " I will give each a shot at the caulking as it's difficult to keep a good clean bead. I raised my hand and asked to go first. I did the first mirror, he looked and announced, "Greg will be doing the caulking."

I did a lot of siding caulking one winter.
The second result definitely tells me that I don't need to try any other path.
