Incorrect SMART attribute label for Crucial SSDs - displayed as opposite of true meaning

On a Crucial MX500 SSD (CT1000MX500SSD1) SMART attribute 202 is labeled as "Percent Lifetime Remain" when in fact Crucial documents it as "Percentage Lifetime Used" in smartmontools. I've verified that consistent with Crucial's documentation the value starts at 0 for a new drive and increases over time.

The documentation from Crucial is available at:

The documentation as written does not state specific models and appears to be applicable to all Crucial SSD models. While it is possible that other attributes are labeled incorrectly (the documentation covers a few) I've only checked attribute 202.

I've been looking at the raw value which is the percentage used. The actual "value" in the value column is correct (the percentage remaining). I've marked the ticket as resolved/wontfix since this was an error on my part.
