Hey guys, so I finally made the jump to SD and right away I can tell I am going to have a lot of learning to do. I dialed in idle pretty good I would say, but I am completely stumped on cruising. I'm not sure what I am doing wrong but I posted a cruise log for anyone willing to help. What I do notice is that when I use SD VE adjust (SDRatio) vs SD VE adjust (CombinedFT) I get completely different suggestions for each. Most people I see use combinedFT and that gives me some very random suggestion and the upper left spots of my VE Table which end up looking like bad "hot spots" on my table. I'm having a hard time grasping what to do here.

Anyway, I added a cruise log from last night titled "sd help 2" and then one from today after some adjustments titled "cruise"

Thank you in advance

Just got done doing a cruise log and I used SD VE adjust (combinedFT) and it gave me these values. This is what's confusing me. I'm not sure why it's so random like this. Is it because just global is off?
