Olypaid rules?

Hey ive been reading the rules of the Olypaid and kinda confused of how it works so any help will be appreciated,

1st Question: Can i fight afew ppl at the start of the competition (about 3am my time finishes at i think 7am :confused:) or Can i fight afew then log off when it gets abit too late?

2nd Question: In the section where is says class only olympaid , (im guessing thats for only my class of dagger , TH) ...Or is it for all classes of daggers including Plain Walkers / AWs ?

3rd Question: Can i fight the same person more than once also if at the end of the fight both players did the same amount of damage (or none) ...what happens then?

1) You can fight as many times or as little times as you like during that time period.
2)You can fight every single class or just your own class, not type, class.
3)You can get matched with the same person multiple times. If the damage for some rare reason is equal then its a tie. Also if no damage is done it is a tie. No point lost on either side.
