Unfinished Holes and Conceded Strokes
A player who starts, but does not complete a hole or is conceded a
stroke must record for handicap purposes the most likely score. The
most likely score may not exceed the player's Equitable Stroke Control
limit, defined in Section 4-3. This most likely score should be preceded
by an "X."

NEW from the USGA 2016 Hcp. Manual...
Playing alone and necessary peer review: ...scores made while
playing alone will no longer be acceptable for handicap purposes.
(Sec. 5-1: Acceptability of Scores)
Anchoring and posting: ...a player who anchors the club while
making a stroke during a round and fails to apply the appropriate
penalty or an adjusted hole score (Section 4-2). Since the score
would not be reflected as playing under the Rules of Golf, it
would be unacceptable for handicap purposes.
