The "Blupping and Blup Schedules" topic pinned at the top of this forum has a guide that will match the New Forest skill set.. Blupping requirements haven't changed over the years, so these still work, and the one you have should probably do as well.
For the New Forest Pony, you'll want to follow one for a breed that matches their skill set. A purebred Forest pony has a stamina, jump, dressage set, which matches Cross Country.
I don't follow a schedule, so much as a general guide, or rule of thumb. I train up the two supporting skills, and leave the primary skill for competition low so I can enter low difficulty. Since the New Forest pony has that cross country skill set, I'd train up dressage and jumping, then enter low level cross country. Once the wins are in, I'd finish training stamina.
Or, if you have the VIP per to change specialty regardless of age, you could train up stamina and dressage, then enter low level pleasure and reining competitions for wins. Then finish jump training, and you'd need to enter a comp that offers jump skill to finish bolding jumping.
