Exploring the Mona scale. How valid is the Mona scale in todays piking?

Pike are being caught now more than ever so does this old 'length = weight' table stand the test of time? Let's guess, measure and weigh some pike to see which method is closer.
Filmed over a year, I had 15 pike on film being weighed and measured, obviously it'd be a boring video with 15 so just used a a few choice clips. Despite this, the results were the same for those pike that didn't make the final cut. It certainly was an interesting project!

Daiwa scales upgraded to RH Carp Spirit scales during the year.
