Since it seems there is some confusion in what is being asked here, and PPRuNe has a limit on what can be asked in a poll question, the OP is seeking a response to establish by what difference you avoid (or don't avoid) cruising at a specific height on a clear VFR flight.
Not what actual height you choose to fly.
Not which direction you are flying.
Not what is the terrain clearance.
Just by how many 100's of feet you may choose to avoid a semi-circular or quadrantal cruise altitude, to reduce the risk of meeting someone else at the same height.
The OP requested a random order to avoid the donkey vote: I think! Since a poll keeps bumping the thread to the top of the forum with every vote I have put a limit and the poll will close next Wednesday,
