0% is included in the calculation for the cart acquisition rate

The results are fine because they are taken from ByDate, but the product pages are taken from ByASIN, so the average is lower than usual because it includes products with 0% of the total.

However, it is wrong to exclude all products because some of them actually have zero cart acquisitions.

The cart acquisition rate is cart acquisitions/pageviews.

Therefore, it is better to take the average only for products with pageviews > 0.
