Default AFR target table and AFR target gauge

I have a significant difference between the AFR target table and AFR target gauge.
I switched one of my gauges on the megasquirt GUI to "Target AFR" to see how it was interpolating between points. When I did this I find that the target AFR displayed in the gauge is well below what the table says. To be specific the table has an input of 14.7 and the gauge has a value of 13. This is an area in the table where the 14.7 is surrounded by similar values, nothing that would warrant a target of 13.
When I change the value in the table, it changes in the gauge so I know they are connected and it seams to be a linear difference between the values. I change the 14.7 to 13.00 and the gauge has a value of 11.3.


Any ideas?

well, it looks like the gauge reads exactly 1.7 points lower. Wish i could help, it is kinda weird though.
