Nice videos. I use the same mash tun and no longer measure the water additions for my 23l length brews nor do I preheat the mash tun, I use 82c water from start to finish. It's really lazy but it works brilliantly.
Half fill the (cold) mash tun with 82c water, dough in and if necessary add a litre of cold water to get near 67c (I usually don't need this however). Lid on and no wrapping the mash tun at all, 90 minutes later it's lost 2c absolute maximum. Fill to 1.5" from the top of the mash tun with 82c water (usually raises to about 72c), stir and leave 10 minutes. Usual recirculation stuff and run off, fill again to within 1.5" of the top with 82c water (hit about 77c-78c), 10 minutes etc. I usually end up with around 30 litres which is ideal for my 90 minute boil. If I'm slightly over I just boil harder for longer (2 elements instead of 1) or just boil it a little longer.
Looking at your videos your mash tun was filled to exactly the same levels as mine. It helps that I tend to make beers that are usually 5% +/- .5% ABV and rarely stray from that but I know I could tweak it if I went higher or lower anyway.
