But doesn't the larger D rated thruster require more distro?
Also, for me personally, I can't justify wasting pharmaceutical isolators to G5 D rated thrusters.
One can alter there distro by making sure to turn off any and all non essential items not needed. Example, if one is in process of flight, then they don't need any power dedicated to the the availability of the SRV. Shutting it off vs just setting a higher priority makes a difference in power availability of any or all other components if and when needed.
Example, most know how to set priorities and do so. Thus with you priorities set the way you want, and time the duration of your laser's before complete depletion. Don't adjust the priorities, shut off any and everything non essential to the process of firing your laser's and time the duration again. They will have additional power available, thus last longer.
Personally, I make sure to have all priorities set. Then depending on my agenda at the time, make sure to shut off any and all non-essential components not conducive to my agenda. What one considers essential is up to themselves. Because one can be interdicted at any time, a noob might think that shutting off weapons would be asinine. But an experience Cmdr, who know how to win a mini game more times than not, and if it's the later, knows how to low or high waking, can and could considered any weapons to be non=essential. I personally flew a Python for a year and a half hauling passenger point to point as well as sightseeing, hauled all types of cargo and didn't have ANY weapons installed any where. And not once during that time though I was interdicted hundreds of times, did I ever need them.
Now I have weapons and actually seek out various combat situations, thus i now have to make sure they have sufficient power to get me through any and all situations I get myself into. And I do so by making sure that any and all components not conducive to the combat and or ability to do a statistical retreat (run) is shut off.
