Default What does the shape of the VE table tell you about your tune

I'm curious to know what the shape of the VE table can tell you about your tune? I've dialed back my spark table based on my knock sensor logs, and then tuned fuel accordingly. You can now see this large trough of area that required less fuel because of the reduced timing. At the 4900rpm region in the 120kpa to 140 kpa the timing changed by almost two degrees. This resulted in a significant increase in the required fuel at 4900 rpm compared to 4300 rpm.

Should I reduce the timing in some places in this transition to smooth the slope of the VE table.

Here are my AFR, Fuel, and Spark tables
