Id look and see what you can do to up your efficiency or factor in low efficiency when putting together your grains next time.
Agreed. I would expect a 3.8% beer that was mashed quite low to taste thin. Definitely make sure your volumes are on. If they were correct it looks like you're down around 53-54% efficiency. I'm not in the group who thinks you should chase ever increasing efficiency, but I would at least try to get up around 65% or so. First I would check our crush. It sounds like a batch sparge, what is temp of your sparge water? You don't need to let it sit long when sparging but do stir really
well. What kind of tun are you using, is there a lot of deadspace or did you have a lot of leftover wort?
