Hey Andy - You really are not shorting yourself anything. When you draw up your dose there is T in the needle and the hub of the syringe - so when you inject that left over you see is just replacing the stuff that was in the needle when it entered your skin. It is kind of confusing, but trust me ( I have to explain it to clients at work) you are getting all of your dose. In the medical world it is called hub loss or dead space, and it is accounted for when syringes are made. It is also why a 10 ml vial that logistically should last for 10 1 ml shots ends up only having enough for 9 shots plus a little extra.
The easiest way to look at it is - when you draw up your dose and push the plunger up until you see the drop at the tip of the syringe you actually have a little more than what the marker is. So if you draw up a 1 ml dose, when you see that drop at the tip proving the needle is full, you actually have 1.05 mls, then when you inject, that .05mls stays behind in the needle and 1 ml goes into you.
Ok - shutting up now...hope that made some sense
