Again, no. You do not need all HQ3 ingots to make a HQ3mortar. And +1/+2 ingot can net you a HQ3 mortar. Especially when dealing with a finished item, 200/300 + quality is possible to get the item you are looking for.
So your saying you can hit 650 quality on a synth using HQ3 mats. That means you can hit 450 using HQ1 mats. If you think that is an insufficient level in order to HQ3 a finished item when you have 'touch up' at your disposal thenI don't know what else to say. That's just false.
