'Uncertain_IntialValue’ in OPC to DB transaction

I have an opc tag with linear scaled mode set (10:1) and I am storing it to a db using OPC to DB transaction group.

If the tag’s quality has/becomes ‘Uncertain_IntialValue’, what would be stored to the db?
Will it be zero, last known value, raw opc value (unscaled), some random number or throw an error?
