Actually using 1 dev mat and using 20 dev mat have almost the same chance for Yamato if you use this website http://unlockacgweb.galstars.net/Kancollewiki/viewCreateShipLog?sid=131.

The data on kancolle-db.net is incorrect because it doesn't take in account individual sample sizes for 1/20/100 dev mats. You can see only 7 Yamatos appeared for 4/6/6/2/100 but 242 Yamatos appeared for 4/6/6/2/20, would you argue that using 20 dev mats have over 34x more chance of getting Yamato than using 100 dev mats?

If you're aiming for Yamato and Musashi, 20 dev mats is better, otherwise you're better off using 1 dev mat for almost the same chance for Yamato and a higher chance of Shioi for prototype seirans (or if you wish to save dev mats for development).
