45.0 mana ratio but it doesnt consider the Locuses and doubling cube,solring etc. so its way higher, usually ulamogs crusher or hand of emrakul are beeing casted not later than round 4, possibly round 3 when im lucky.

f.e.:

Round 1: first Cloudpost
Round 2: second Cloudpost or Vesuva; buying Sol Ring
Round 3: Eye of Ugin; buying Ulamogs Crusher for [6] instead of [8].

but most of the time it takes 4 steps.
