Well, I looked at your log, and according to the "Data" tab, you max on #4 is 11.25, which as you know, isn't right. Kind've off how they're all at "0" for the most part, with the exception of the occasional blip.
I've got an issue with one of my injectors; I have a glow plug stuck in #5, which, interestingly enough, was the same cylinder that was having abnormaly high balance rates. I switched injectors 5 & 6, and the balance rate followed the injector (althought is almost seems as if the odd balance rate has "moved" to #7
). If you're going to pull an injector, might try swapping with another and see if it (the balance rate) follows the injector like I did. One piece of advice if you're pulling one or more injector: I'll almost guarantee you'll need a new O-ring for each injector you pull; both mine came out broken, and they cost $8 each! The copper washers probably can safely be re-used (I re-used mine; they cost $8 each too!). I do wish I had access to a bore scope to have a look-see at the messed up glow plug in #5.
BTW, I have what seems to be an abnormally large amount of blowby (lots "oil scented" vapor coming out of both the PVC hose and oil fill), but near as I could tell, all cylinders (except the one that I couldn't get the glow plug out) had compression, although I'm not wure just how accurate the test was since I had the one glow plug stuck.
