Why aren't tables smooth?

[serpa4]

Was looking over various tables and see that some are more peaky then the rockies. Huge vallies and mountains etc in the middle of tables. Logic would think they need to be smooth. What is the point of all the spikes? Specifically Torque based fuel Med altitude adjust is wow, but low is flat.

I don't know for sure, just suspect it has to do with a manual histogram process. EFI reverse engineered the histograms, exposing the inefficient human process.

Wonder if smoothing will make anything better?

#1 Reason:

They first start with a math model then make corrections to it to fix areas where emissions fail.

Even the Main Injection Pulse table has been heavily edited after the math was done.
