Greetings

I read Jin Pal HKD has forms,

1. Who created them & why does JP HKD think they're beneficial, since it's not a traditional a part of HKD?

1b. Are they mainly for kids and do they take too much time away from technique pratice, meaning JP has less techniques as part of the curriculum than Traditional HKD?

2. What are the froms like, TKD (Hard), Kuk Sool (soft), etc?

3. How many are there and what levels are they taught?
