Using the data provided by the fellow tenno I got ~28.31 (kept track of a lot of decimal places) so I'd say 30 is about right. It should be noted however that the Magus Husk arcane reportedly can give 200 armour at max rank (i.e. totalling out to 230 armour and ~43.4% damage reduction). With the Unairu passive, you get ~60.5% damage reduction if multiplicitive, and ~69.7% if it's additive.

If I were you, I'd personally go for the Vazarin health passive first before investing in armour since that has much more clearly drfined values in game (hence you'll know what you're bargaining for) until further information is uncovered :)
