As of right now (7/22/2020-US 11:45 AM EST,) the tier one vest has an armor rating of 0.7, the tier two vest has an armor rating of 0.5, and the tier three vest has an armor rating of 0.7.

I don't know why the first and last vest have the same armor and the middle one has 0.2 less armor. ¯\_(ツ)_/¯

I went into the unturned files and found that standard military vests have the same armor rating of 0.7, so this mod won't be any more protective then what is already in the game.

The numbers are the multipliers, it appears that the tier 3 vest has the wrong armor value inserted. This means that the first and third vest have a 30% damage reduction, while the second one has 50% damage reduction. For reference, a vanilla spec ops vest have an armor value of 0.65 or 35% damage reduction, which means that the second tier is already better than the best vanilla have to offer. Assuming that the third tier will be fixed in the future we can assume that it'd have an even lower multiplier compared to the second tier.

New values are 0.6, 0.5,0.3, with the third vest having the right ID

ok thanks, everyone!
