I don't know how much kp I get from tourneys. I knew at one time but I now consider it part of normal collections and just didn't keep up as I added more completed provinces and got more consistent with them. I consistently do a minimum 5 rounds of 10 provinces each week. We pushed last week to help 2 members max their boosts and I did 5 of 20 plus a few round ones in the higher provinces for 4230 total points. Yes, kp addict here, lol! Do you buy kp with boosted goods? That's what I save to use for event quests.
It's less than half the Kp I said, if you don't clear provinces above 10
I counted for 13 provinces, ~5.5 rounds.
If I plan on getting to round 6, I clear 13.
If not I clear 15 to round 5.
For now... will eventually go higher as I progress... I hope
And no, I maybe purchased Kp once with Goods. I don't even know why, lol Maybe it was during the 1 time I finished a Event in 2 days.
Playing the long game, I believe it will come in handy in those harder Chapters.
