exactly what I change to make the board update at the end of the lap rather
than at the end of the next lap? Or to put it another way - update in real
time rather than having to wait for my pitman to set the board up for me to
see next time around.
pit_board = 9.0 3953.4 -100.0 100.0 ; dlat of board, dlong of board, dlong
LOS start, dlong LOS end (last 2 not used)
