Here's my novice calculations, anybody more well-versed, please correct me if needed.

0.5 from Saturday would be 0.25 remaining

0.5 monday would be 0.315 remaining

In total, (in theory) you should have about 0.565 left in you
Adding another 1.0 tomorrow would be pretty close to what you'd see if you dosed 1mg last Saturday, i'd say negligible difference.
But, as i've read it, initially you're just building up your levels, so I am guessing you may metabolize it faster in the beginning until you get your levels up and more stable.
