Affiliate Marketing Secrets

Please could you explain a few show jumping rules to me, preferably including a complex rule (like the ‘off side’ rule in football is a complex rule).
clarification of faults would be helpful.
Refusal = 4 faults
Knock down = 4 faults
Time faults = ???
Allowed 2 refusals (8 faults) then on the 3rd you are eliminated.
Unplanned Dismount (fall of horse or rider) = elimination.
Is there a maximum amount of faults that you can receive before getting eliminated? Like if you get a refusal (4 faults) then 2 knock downs (8 faults) meaning that you get 12 faults does that mean you are eliminated? Could you knock down every jump and just gather lots of faults but not be eliminated?
Do the rules change between affiliated and unaffiliated?
Like, my riding school does unaffiliated show jumping competitions and doesn’t have time faults, time only comes into consideration in the jump off.
This is for my PE GCSE course where I need to write in detail about 2 rules (preferably 1 complex) so any info regarding show jumping is helpful.
