If it were me laying the remaining bricks, I'd be inclined to lay the rest up the right way. Mainly because I can lay them about four times as quick that way. But I haven't had your wealth of experience of laying them inverted have II am halfway through another one now. Shall I start doing them the right way up? This means at one point there will be two beds together.
When you're laying them up the right way, once you've laid the bed joint, you can lay the course of bricks on top of it without returning to the spot board. Each brick you lay, you cut off the excess and use this to put the joint on the next brick. Since you will not have enough excess squeesed out of the joint to fill the frog, you must be going back to the spot board for every brick, just to fill the frog.
Mastering this technique of using the excess squeesed out of the current brick to joint the next brick is the key to getting your speed to really take off. I can assure you, it will halve the time it takes you to build a wall. It also makes you a very clean worker by necessity. You're less inclined to drop or smear that excess mortar, when you see it as the material for your next joint.
