Thoughts on "Impression Timer"

Yet again some nice technical updates in Version 3.3.4! 

This part has caught my eye:

'' Starting with 3.3.4, impressions will only be counted towards a post if the member remains on the page for a sufficient period of time. By implementing a short timer to register impressions, another step is taken to ensure only genuine and real impressions are being registered. ''

Has anyone felt the impact of this feature? Does anyone know what's the amount of time set for impression to count?

I guess all the "👍 " comments will not count now as those never looked organic to me
