OK, I'm a fool, I see it now.
Using those numbers, I see DDA as a 0 handicap (0.4955 actually, rounding down), and agree with your calculations for Dan and yourself. Having DDA at scratch makes the calculations simpler than having him giving back a stroke. If you're playing any kind of match play, I always play off the low handicap in the competition, so even if he WAS giving back one, I wouldn't be subtracting one from him, I'd be giving you and Dan one more stroke apiece. This is consistent with Appendix C, Handicap Allowances.
For you, getting 7 strokes, I believe you should have 4 on the first 9, and 3 on the second time around. This is consistent with the recommendation in Appendix E to allocate the Odd numbers to the front side unless there's a compelling reason to rate the back 9 as the more difficult side. Obviously, since you're playing the same 9 twice, there's no compelling reason.
My father gets numerous golf balls from my Aunt who lives left of the #7 hole at Tanoan Country Club. Left is better than right, but unless you live behind the tee box you're going to get balls landing in your yard.
In a friendly 18 hole game over the weekend, due to increment weather, the course only opened the front nine.
This is typical conditions on Nine Hole Courses, when playing a 18 hole match, I assume. @DaveP043 need your help, I'm confused as usual …
On pages 63 - 64 Rule 6.1a of the new Rules of Handicapping.
Calculating the course handicaps are the following - DDA (-1) Dan (2) John (5) I'm assuming this applies for 18 holes? Now is my confusion on this matter.
Would DDA lose a stroke on the Hdcp Hole #17 which is the 8th hole on the front side?
Dan would receive 1 stroke on Hole #3 which is the #1 handicap hole on the front side?
John would receive 3 strokes during the first nine holes and 2 strokes during the second time playing on the front side?
Hole #3 (#1 hdcp) Hole #2 ( #3 hdcp) and Hole #6 (#5 hdcp)
Is my assumption for stroke allotment correct?
One note I discovered,18 hole course handicaps were different due to course rating from only the front.
The CH for our 18 hole course are, DDA (1) Dan (4) John (7) we each had a difference of two strokes.
Handicap Index - DDA (1.3) Dan (6.0) John (8.5)
Here is the course rating for the front nine at our course - DDA played the Blue, Dan and I played the Blue/White
