From a business writing standpoint? that whole sentence is superfluous. The whole thing is an insertion of humility, something that is important when speaking about yourself to other nerds, but is essentially social fluff.
My takeaway is primarily not that I did verbosity wrong, though certainly that comment wasn't right, but that the verbosity itself is the problem.
Take, for example one of the bits of writing I'm most proud of:

We had a real editor, and my co-author had significant writing skill, but even so: Look at the Scheduling for providers section; that was mostly me.
This is about what I had been aiming for in my business communications, and while I still think it's a reasonable bit of writing for a semi-technical audience, it is far too verbose for a business email.
If I was sending that same passage to a business person, I suspect the optimal format would be something like:
"We will allocate CPU based on how much ram the user purchases."
The rest is technical details and fluff. When dealing with a businessperson, the technical details are my job, not something they care about.
I think that my primary self-destructive impulse here is that I want to throw out technical details, in part to prove that I actually know something. I need to restrain that bit of ego, as worrying about the technical details is what I'm (hopefully) getting paid to do.
