I don't think you should be trying for yamato using only 1 dev mat. According to kancolle-db.net, there's a 5x more chance to get yamato using 20 than just 1.

So unless you have tonnes of resources but no dev mats I suggest using 20 (and 19 dev mat are easier to get than 4/6/6/2k x5 resource imo).
