Differences to qualification queries in TPC-DS kit templates

Hi! The queries for qualification and the answer set in this repository are quite beneficial for us to verify our research database Hyrise.
We have noticed that some of the queries have a different form than those that can be generated with the official TPC-DS kit. For example, query_qualification/39a.sql includes a factor in the line stddev_samp(inv_quantity_on_hand)*1.000 stdev, that is not part of the official query template.
Because we want to benchmark our database as close to the TPC-DS standard as possible, we wanted to ask why these changes were made?
Thank you.

Probably because I used an older version of the kit
