It really just sounds like a gear problem.
Crafting 4000 collectability hand-in's is almost as easy as synthing two star food in 2.0. You can use the most basic rotations in the world to hit 4000 Collectability.
I'm getting 5100 Collectability on Red Scrip hand-in items just using a generic 100% success macro rotation. No "Good"s, no Hasty Touches, no HQ ingredients, no two star Blue Gear. Its nothing more than 5 Basic Touches and your usual Byregot's Finisher. Progress can be completed with Ingenuity II and four Careful Synthesis. (Just toss in a Waste Not so it doesn't cost 40 Durability.)
If you can't hit 4,000 every time you need to increase your control. Try an FC buff, Seafood Stew, some melding, or a Hasty Touch rotation for higher Inner Quiet stacks. These red scrip hand-ins really are one of the simplest things they've thrown at crafters thus far.
