Normally - you shoot a prospector limpet, scan and decide to mine an asteroid or not depending on the content. After mining for a while, you get a feel of your mining laser, how much it drains the weapon power distribution, recharge time, etc.
At times I'm low with limpets, I would just shoot the mining laser at asteroids and see the radar if it outputs the material I wanted, watching the Contacts Panel as well.
Option 1 - I may only then launch the prospector limpet to check the remaining %.
Option 2 - when really low with limpet, I just shoot till the radar don't show any output.
In these situations, I got a feeling the depletion rates are much faster. Sometimes after firing a test shoot for materials and only launch the prospector limpet, the remaining shows as low as 50%. If begins with a prospector limpet, this short burst would normally only cause a small depletion of 10% to 20%.
