I don't know about that. You can reliably move up to 4', 11" while ethereal (you only have a 50% chance of becoming corporeal while moving through a solid object per 5 feet travelled). I think it's reasonable to conclude from that that you can reliably time your five feet of movement while you're on the material plane.
Hypersmurf said:Your speed is reduced to half while you're Ethereal, though. So when you're blinking, some of the time, a 5' step is prohibited.
The 20% mechanic would seem to fit, the more I think about it. You're attempting to take an action that only works if you're not Ethereal at the time. Just like attacking or casting a spell.
