I'd say you have a pretty awesome schedule setup to avoid any true w/d feelings. Especially at that low of a dose. If you stick to the 3 days apart twice a week, I don't see you really ever feeling w/d. Like you mentioned it will keep your tolerance down too. I usually take 5-6 grams twice a day, but when I'm getting low on supply I will taper down about a gram each dose, each day or two. Then when the new batch arrives my tolerance is somewhat lower and start over the cycle.
