Uh, one thing to keep in mind: your wet/dry works MUCH MUCH MUCH better when the media is exposed to air. That's the "dry" part of a "wet/dry", and that's why they are also called drip systems.
After a certain point, increased water flow keeps the media constantly covered in water and dramatically DECREASES FILTER EFFICIENCY.
From a filter perspective, turnover rates need to be high enough to keep ammonia/nitrite at 0. That's it. No more is needed. As Rallysman mentioned, 3x can be plenty good enough.
If you are worried about water movement in the tank to avoid any dead spots, you can use a power head. If you want more oxygen, then you can use an air stone. But let the filter get plenty of air directly on the media by avoiding a constant waterfall of water.
BTW, I suspect 10x beliefs originated with HOBs. My HOBs tend to slow down over time as the media clogs a bit. 10x easily drops to 5x or less, so it makes sense to get a filter that can move more water when it's shiny and new.
The 10x turnover rate mantra should never be applied to a wet/dry since the flow should really depend on how much water can move through the drip plate and still let the media get air directly.
Just my experience...
