CPU calculation not 100% accurate

For the more accurate Co-Op range:

Co-op range calculation: Your Level, +/- (10 + 10% of Your Level). This means a level 100 player using the White Sign Soapstone can be summoned by others who are between the levels of 80 to 120.

The above formula cannot be applied to the host, as the range is calculated be the player using the White Sign Soapstone. If a host wants to know if they can summon a friend or not, calculate the range from the phantom's perspective to find out if the host's
level is found within that range.
