thats actually not the way it works. the owner determines who has the ability to even use a SP within the tools section. 2 will automatically replenish at the end of the clash. meaning if your club has 10 SPs and uses 5 of them, at the end of the clash you now ("should be") at 7. if you use all 10, then you will be at 2. so if a club uses all available SPs during a clash, at the end they will,( "should be") at a minimum of 2 SPs. the ideal way to use SPs, imho, are to try and figure out witch of the courses & conditions that you feel are the best for you to utilize the SP in the first place. hence getting the better score & multiplier! you'll only get a few different scenarios during a CC clash!
Hope this helps someone!
