Forgive me if I'm just being stupid, but the gap numbers between 2017 and 2018 don't make sense. I find discrepancies in some if not all of the first 4 weeks, most importantly culminating in the gap between the totals being incorrect.
2017 has a total of 1,195,113 after week 4, 2018 has a total of 1,296,349. So that's a lead of 101,236 for 2018. But the yearly difference shows as 106,488 in favour of 2018 as I understand it.
I've been racking my brains over this just in case I'm being mental, so if I am, again, I apologise,. If not, is there a reason the gap number (general totals for each week seem to add correctly) are off?
