Are we really in disagreement here? Playing devil's advocate is all fine and good, but remember that the OP is pulling 2.5oz liquid plus 0.5oz crema from 15g of freshly roasted coffee grinds. Experimenting with smaller volumes (at least for "standard" double espressos) seems like sound advice.
Oh yes, and since this post started, I having been pulling shots with a total volume of 2 ounces, maybe just a smidge more, vs the previous shots that were getting close to 3 at times with crema.
I am much happier with the lower volume shots. A bit of a harder tamp and I am getting the same extraction times for much less finished volume.
