I also agree with above, it you're really tired enough that your form and technique are fading, it might be better to just end on a good note and save the rest of your ammo for the next trip.
Now the other side of that, if pushing through when you're tired you really have to concentrate to keep technique and form up to par. That can be as good thing because you are making progress by increasing endurance. That's like the idea behind doing free throws right after to run a bunch of windsprints at basketball practice. Because in a game, you will not be fresh and unwinded....you will be hot, tired, legs shaky, breathing hard....so it was making us concentrate through the tiredness (word?) so that we shot our freethrows well and made them count.
Or you can also bring up the point that will you really be needing to shoot when you're tired and flustered? Could be yes, could be no.
