Does anyone know why sometimes if the instant salinity says -3300 the amps will be around 5.80 and then other times with the same instant salinity of -3300 the amps may be over 6 at say 6.08?

The instantaneous salt is measured by conductivity. It has nothing to do with the amp reading on your panel. The amp reading is how much current your cell is using to generate chlorine. If, however, your amp reading is 0 then your salt reading will also be 0 because the cell is shut down.
The AquaRite does not measure salt by conductivity. It uses the performance of the cell. The salt is determined by a formula based on amps, volts and water temperature.
So then amps and instant salinity are not directly related. It is a combination of amps, volts and water temperature. Maybe this thread needs to go to the deep end but I'm just interested.

Conductivity is water's (or any material's) resistance to current flow. It is calculated by the ratio of amps and voltage which then must be compensated for temperature.
The AquaRite measures it's ability to convert chloride into chlorine at a specific water temperature. It does involve the flow of electrons, so it is a type of conductivity. However, it's not the same thing a conductivity meter uses. The Jandy and Autopilot use a separate trisensor, which does use a conductivity meter.

Ah, I stand corrected (or more accurately "educated" )
That said, I wonder what the Circupool SI series use for the same calculation? Conductivity meter or the ability to convert to chlorine.

Would the Jandy and Autopilot be considered better or more accurate than the Aquarite? In your opinion, does it matter, as far as accuracy goes, how the units calculate instant salinity?
Units with separate salt sensors don't have the problem of reporting incorrect salt levels when the cell plates are wearing out. The AquaRite also suffers from incomplete temperature compensation, so it's salt readings tends to be off when the water is cold, even though it does take temperature into account to some extent.
