Review comment:
I checked, I thought it was worth it. `i_current_price` min is
0.0900000035762787 and max 99.9899978637695; thus, assuming uniform
distribution, BETWEEN will filter ~70% of the data. On the other hand, the min
for `i_manufact_id` is 1 and the max is 1000; assuming the same, IN will filter
>99% of the data.
