Since the birth of the world, there has been the problem of the overall depiction of changing a site's position in Google's results for a set of queries (keywords). How we can present the average increase or decrease for a set of keywords, which however have different gravity.

That's why I turned off the lights, I lit candles, I put a drink and with low music playing in the stereo I wrote an article on how can we calculate the average of changing the position of a website in google results taking into consideration some gravity factors. I've done an excel file for easy calculation.
