Difference between Armour levels?

There are three levels of armour in the game, I am wondering how much difference there is between level 1, 2 and 3?

Is there like a spreadsheet somewhere showing this for each different piece of armour?

Level 1 absorbs 30% of incoming damage, level 2 absorbs 40%, level 3 absorbs 55%.

This spreadsheet contains a breakdown of the damage in the game whether it be how much damage a particular gun does or how much damage it does to a certain piece of armor and the damage mitigation for each piece in general:

I would also recommend heading over to the PUBG subreddit (r/pubattlegrounds) for a lot of other helpful info
