I started Tuesday working probably about 10 hours a day - (I think your estimate was fairly accurate, Chris), although it seems that interruptions are prominent during this time.
I make the puzzles in stages now. This means I can create a bunch of pieces and connector that will work for each cube rapidly, almost in assembly fashion.
First, I make the proper connecting pieces for a chosen number of each type of puzzle. Then I going into a "construction stage" were I put the puzzle together, plastic welding and bonding. Then I may take a break from the vigorous activity with stickering each creation.
I have even found that changing the order in which I create the puzzle allows me to make complete use of the "by-products" that happen to be produced from each style. I start with the 4x3's, then onto the Fusion, Fusion+, and Triamese cubes, following by the SpeedFusion and last the 5x3 Cubes. Out of 900 cubes I creating this particular shipment leaving around 400 raw 3x3 cubes remaining.
I will continue now to create stock from these cubes.
Some puzzles are probably created in less than 15 minutes, but it seems that once I have the connectors made, the puzzles themselves are produced very soon after.
It's an amazing and fun process now.
