Which videos are you referring to George? The 10 or 12 I've watched so far (some repeatedly) and 6 or 7 I've already made have no inconsistencies that I've noticed.
Here's just one example of many. This morning I attempted to transcribe the ingredients of the BIR style plain chicken curry. I made the following notes:
INGREDIENTS
50ml cooking oil - added in two shots, one at the start, then more as an afterthought
1 slightly rounded tsp butter ghee - he said 0.5 tsp
1 level tsp chopped garlic - he said 0.5 tsp
50ml chopped onion - he said less than quarter cup in commentary but quarter cup (60ml) was printed on screen
1 level quarter tsp salt
1 level tbsp diluted tomato puree
2/3 tsp mix powder - he said 0.5 tsp
1 rounded tsp fenugreek leaves - my guess from volume added as a large pinch by hand
Pre-cooked chicken (200ml) with some of the sauce
Big pinch fresh chopped coriander - he said a handfull
Base gravy - 4 chef spoons (approx 120ml) but 1 tsp (5ml) was listed as text on screen
Some chopped green chillis
Further fresh coriander before plating, then another quantity as a garnish
Notwithstanding the need to check quantities, I think the Britisian Food channel is fast becoming the best BIR related channel on youtube.
