You played 2 CT-s in a row. With starting ent of 5 it's pretty normal that you had it @3 after the tie. Remember CT cuts the ent to half, so with 2 CT's you go to 2,5 and then 1,25. The days between games raise it a little. What is there to argue about anyway? If you had ent at 3 before the game and you tied then it's pretty obvious you had it 2,5 or 2,6. I'm pretty sure you have it at 4 before the next game starts.
