battery chart spreadsheet error

[Cutwater28GG]

unless Im making a stupid mistake (quite possible!) i think the spreadsheet calculations are wrong in the as a prop turns battery calc spreadsheet

if I add solar amps shouldn't I see my net power load drop and not increase? i.e. if I add 5 hours of solar I should see that subtract from the total load. right now its an addition.
same with the engine running

Use a negative (-) value for the hours for your solar and engine running time.
