Mysterious I can understand, but shady never. In all my experiences with you, you've been open minded and passionate in both learning and teaching. Heck, you tutored the guy that taught me how to OC in the first place!
I haven't personally bought from you in a while but I believe I understand the difficulties binning brings. Board, CPU, temps, humidity, specific tertiaries, specific bios settings/version, OS, testing methodology, and many more factors play into where your memory tops out. This has come from my experience testing B-Die over the last couple years.
I'd say you're one of the people I trust, and that's something I really value.
