Beautiful block
The 3 things we look for.
1. Turbulence. (disruption of Laminer flow)
2. Volume of water. (amount of water capable of being put through the block)
3. Velocity of water. ( the speed of the water that is being put through the block)
I think if you look at the block...you will be able to judge for yourself which you have achieved...and which you have not.
With that said....I still say beautiful block.
