Bec and Matt are going to do their first recording in front of a live audience at bluedot festival. They will be there at 2022-07-22, pi approximation day. If you're in the audience, mention it when you submit a problem via the Problem Posing Page.
2022-03-14 is pi day. At the time of recording, Matt has just gotten back from Houghton-le-Spring, where William Shanks, who calculated pi to the most digits by hand, lived. There, Matt and a group of 30 people tried to calculate 100 digits of pi by hand. They got only the first 11 digits correct. The full video is up on Matt's YouTube channel. Fun fact: William Shanks' gravestone was bulldozed in the 1970s and his grave lost.
While they were grocery shopping, they noticed that there were some words that may freely be used on products whereas others can only be used on specific ones. In Germany, "premium" can be used freely whereas the word for "chocolate" can only be used on specific products. They'd like to know more examples which are or are not reserved on food products.
Bec spoke to a lot of people to solve this problem. She even took a course and got a certificate. All of her research was limited to the UK. Mislabeling your groceries is a food crime.
Bec explains a bunch of rules and examples, including chocolate and milk vs oat milk. There were apparently court cases against Froot Loops and Cap'n Crunch Crunch Berries for suggesting that they contain fruit. Quite a lot of super markets got in trouble because of their in-house brand names. Bec explains the differences between fruit juice and nectar. Bec explains the difference between natural mineral water, spring water, and plain bottled water. Jam apparently has a lot of rules. Finally, barn eggs only require 15 cm perch space per hen and only 1 m² of floor space per 9 chickens.
A preemptive free-range ding from Matt (with Beardyman undertones)
How much of a public servant's salary is paid by their own taxes?
Matt, having been a teacher, uses teaching salaries for his calculations. Roughly 0.0000006% of the UK government spending came from a single teacher's pay. Over a year, 0.02 pence of the teacher's salary comes from their own salary. Almost exactly, all the tax paid by all parents from a teacher's class is one penny of your annual salary.

Jack notes: The UK has a referencing system for every property, including individual flats/post boxes/structures, even Stonehenge. The UK referencing system is called the UPRN (Universal Property Reference Number). They can be up to 12 digits long. And unlike the postcode data set, which is owned by Royal Mail, the dataset is open data, licensed under the Open Government License.
Jono [Editor's note: Spelling likely incorrect] notes that a lot of Matt's winning options were illegal because there's only one Q and one Z. Matt only upheld the 7 tile limit. Matt accepts that he is wrong and deserves an unding (a "gnid"?).
Ken Floor got a shoutout for finishing their problem submission with "Best wishes, warmest dings". They were apparently trying to reopen the view distance problem.
Two more reviews are read aloud by Matt and Bec.
Matt presents multiple cards to Bec, none of which are her card.
