Firecalc inflation handling (of pension)?

[strathglass]

Wife and I will have a future income stream, inflation adjusted, starting at age 70. I know the value of those payments in today's dollars (actual payment at age 70 will be higher to reflect the annual inflation adjustments).
In our case this is a government pension, but not Social Security (we're not Americans, but it is something similar)

I entered a bunch of data with three variations as follows for the "Other Income/Spending" tab to handle this future income; all values entered in today's dollars:
a) Enter the payments in the Social Security/Spouse's Social Security lines
b) Enter the payments in two of the Pension Income lines (check "Inflation adj." checkbox)
c) Enter the payments in two of the Pension Income lines (do NOT check "Inflation adj." checkbox)

All three results are different: I would have expected one of b) or c) to match a).

Can anyone explain such a result?

Oops - just realized for option b) I had transposed digits in one of the starting year values: corrected that, and now option b) matches a), which is actually what I was expecting!

There are a bunch of Canadian's here, so you are allowed to say CPP (if that's what it is).
