I love your work and I don’t think this is important, but the PS5 numbers for Elden Ring contradict each other in those two charts. One said it went up one unit. The other says it went down one unit. The total number of pre-orders remain the same.
That's because the LE version got kicked out of the chart. It had 2 points.
So... +1 Point for the regular version, and -2 points due to the LE version leaving the chart... -1.
