pdb1: Some people contend that they are not ranked in the count of ranked rounds for the purpose of saturation, tiering up , or averages . Meaning you don't get a round added when played for saturation .
This!
pdb1: This I believe is a gray area and contradicts the definition of ranked .
It is a consensus between the players who have calculated averages in detail. OTOH, the whole matter is gray area because there are no official numbers. The most precise definition in the FAQs is (not verbally), "Bo3 scores do not count in to average calc."
And, they are good in confusing or imprecise wording, thus don't rely on that too much.
See the last quote: It says Bo3, but BDU is excluded as well as Bo5. Speak not of precision, speak not of QA.
Have fun!
