It could well be me answering that 'dog and bone'.....
Don't join midpoint.
Otherwise you will cut in front of bona fide downwind traffic who will least expect a 'Cabair'-style midpoint join.
It has never been standard procedure. Well, not since 1975. It would have to be one hell of a wind for a C152 to make 800 ft aal by the upwind numbers. Level at 400 aal on climb-out or go-around in orderto miss the 800ft crosswind leg traffic over the upwind numbers.
Follow runway 14 for 07 right-hand and you will miss Yateley.
None of this is difficult.
