The only time it makes sense to complete the trip in this TP year is if the OP is going to miss out on gold (or some other status higher than silver).

If this trip (or half of it) is the difference between 300 and 600 TPs, for instance, the soft landing will take care of silver status.

Otherwise it makes sense to have as much of it as possible on or after 9 August to get a head start on qualifying for gold next year.
