Is there an appropriate way to shorten the phrase "upgrade and downgrade"?
I am writing a paper and have to use this combination frequently. I am trying to find a succinct way to let the reader know I'm referring to both upgrades and downgrades without making them read the phrase over and over again.
I was thinking something like up-/down-grade, but if that is the case, I'm not sure what the appropriate punctuation would be.
Edit: Forgot to add that this is for a scientific paper so meaning and brevity take precedent over style.
Here is a sample sentence:
"An up/downgrade refers to an objective comparison of the consumer’s currently owned product and its potential replacement."
An up/downgrade refers to an objective comparison of the consumer’s currently owned product and its potential replacement.
