I'm not sure... I stole this off twatter but I thought it was based on CPI so it would be percentage change but I don't know. I do think that import prices raising it would be dumb to not raise your price just under your foreign competitors. If you didn't you would be leaving money on the table but that's a different analysis
I don't think it's based on CPI. The fluctuations are too frequent for this timescale. They must be plugged into some real-time daily or weekly data for some kind of import prices / domestic prices. Amazon price data maybe? Not sure what else would be avialable that is so high frequency.

The basic point is probably right. I've seen other reports showing the same pattern.
I just find the price trend surprising.
