There is a decreasing coefficient for fights versus bots when the level of account "does not match" the Arena.

You must be at least level 9 of your account at the beginning of Arena 8 in order to get at least some points for a fight versus bot. The farther inside Arena 8, the higher the requirement. For example, starting with a 2700 rating, you need to have a relative level of 9.25 (i.e., level 9 and 1 \ 4 of the experience needed to get the next level of your account. To get full points for a fight versus bot at the beginning of Arena 8, you need to have at least level 10 of your account.

For fights versus real players, this coefficient does not apply.
