Stupid question

I dont know if anybody caught it but I asked this question in an older post, but nobody answered.

For the WOT values in the timing and fuel tables (at 100kpa), would it be better to have linear values contrary to what GM did and have them jump around a lot ?

For example instead of having them 10,13,15, 11,18,12,10 etc have these value gradually increase or decrease in a linear pattern like : 10,11,12,13,14,15,16 etc or 10,10,10,12,12,12,12,14,14,14,14 ?

Am I making any sense here ? lol

It not about what you want, but what the engine wants. Test it and find out.
If no definite improvement, then I'd highly recommend following the stock pattern.
Once you have the cruise and WOT timing right then you can play alot without fear of hurting things in the transistional area.

Well it's not about that. I already have the cruise and "non WOT" values down to what the engine likes. I guess I was just wondering why GM did that.. instead of steadily increasing/decreasins the values why did they have to go up and down so much.

Short answer is to avoid detonation.
The closer you run to detonation the more the tables will be erratic.
VE changes thru out the rpm load ranges so the timing must also.
