No problem, I'm just as interested in the accuracy of the comparison as you are. Can't say I've been on the wrong side of those kind of activities from Kurfurst myself. According to Kurf the second chart I quote is a DB605DC at 1.98ata using C3 fuel where all the rest are at 1.8ata, and this explains the discrepancy. Which means that the K4 FM has the ROC of a K4-C3, and the K4-C3 is far too high (at about 5200fpm where it should be ~4900fpm). The K4 FM should ideally be closer to about 4400-4500fpm.
