Stanley Cup Geographic Center

We're approaching 100 years of the Stanley Cup being awarded to solely to the NHL champion. After two years of the Florida Panthers winning, they did not make the playoffs. The geographic center of all Stanley Cup winners has not moved very far - it's now 500 miles from the first winner, while the most recent winner is 1500 miles from the first winner and 3000 miles from its furthest competition.

Zingo

 The bar was set pretty high with the kids' game Spot It and several analyses followed:

On the other hand, there's Zingo. Three copies of each tile exist, and gameplay proceeds like Bingo except only one player can claim a called tile. 

The game has six green cards and six red cards; the green cards are advertised as having fewer shapes in common. However, the pair on the right shares five of nine, more than nearly all pairs of red cards! Meanwhile, the left pair shares only two. The player with the left card has a definite advantage. 

This game would benefit from better cards.

Political Parties and Sports

Of the last 30 Super Bowl winners, 18 had Republican Governors, and 18 had Democrat Presidents.

States with NFL teams don't have significantly more Democrat governors.

Top Big Band Albums

Composer and bandleader Darcy James Argue announced 30 + 30 Essential Bigband Recordings. Half of them predate the Grammy for large group, but still I expected more in the union of these sets. 

The most popular thing I have ever Tweeted, bar far, was the thread of 30 Essential Bigband Albums that I posted last year. It’s time for a sequel. https://t.co/w10iINZr2z

My Euler diagram is obviously loose. You can find Miles, Miles + Gil, Miles + Quincy, and Quincy separated, as well as ghost bands separated from their originals, but otherwise I didn't fret too much over different recordings or eras representing the group.
