Barometric base table incorrect 5.7hemi?

With reference to the Spark>Advance>Barometric Pressure>Base table as shown below for the 5.7hemi.

I understand that as you go up to a higher altitude area as opposed to sea level, your time can be advanced quite a bit.
So, should the baro base table not read + instead of -, meaning add timing as opposed to take away as per the table?

nobody can add comments about this? This Baro timing table can have a big influence on a tune.

Not really used as far as I remember

Thanks for your comment. As I understand, this table is a direct adder to timing/spark and when the MAP reads the Baro pressure and finds now at higher altitude, it will automatically adjust the spark PT and WOT tables. For this reason I regard it important to have this Baro table correct and I know for fact you should add timing for higher altitudes where the baro reading is lower.

There’s a comment in the forum about it being counter intuitive, can’t recall where. For mine I just zeroed them out in the baro range I operate in.

Thanks sPHYNX. I live at sea level but often go up country. Will check effect. Last time had the table still stock setting, but now have changed it to advance timing at higher altitudes. So I can now compare results.
