We played, that's about 15 members of my CC. We won 5 or 6, lost one Clash IIRC, and finished about 100th with 7,000 points. This is the usual result, and we might be better if we'd accept members from other time zones - no Clash at night! Results are irrelevant because we buy no passes (at least AFAIS, checking the profiles of the most actives), and there's no "prize" to strive for.
I like to share a game with my members, look what's possible, and I play more than usual, eight rounds in two days. Expenses: Neglegible, the better part of the sleeve I bought a week before.
