To be fair, the layering of AS0 was higher than 3D of AS0 which are partly caused by the assembling process in sampling, but that turned out to be a positive effect.
So even if we follow exactly the 3D it would still be up to our control of the sampling process not only the 3D alignment.
Also the fact that there was a late request to change the center stone from a heart-shaped to be a trilliant didn’t help with the speed.
So to sum it up, we are responsible partly to this delay, namely 3D modeling and sampling but those are not the only reasons as other factors also involved.
