Remove the Parenthesis S
Maybe this is just a pet peeve of mine, but why is there a (s) for the Mission Days Attended and NL-1331 Meetups Attended stats, but not for any other stat on the profile?
If your line of logic is that some people may only attend one event ever and that (s) allows the stat line to be read as possibly singular, that same line of logic isn't applied to other events... for instance, Intel Ops which is lacking (s) and certainly an event that there has been less opportunities to attend than Mission Days.
I say remove the parenthesis in the name of consistency, and in support of repeat participation.
Also, while I have you here... given the above screenshot, I'd like to give Niantic another opportunity to explain why they zeroed out the Unique Event Portals Hacked and have left the stat hanging there.

OPs(s) or Operations(s) isn't a word
The each event was a collection of operations please find a better example
...
Could mission day be renamed?? To missions day??
Maybe you're having trouble seeing the screenshot, but the stat is called Intel OPs Missions. Try again.
It doesn't seem like you're comprehending. Picture this:
First Saturday Event(s)
Intel Ops Mission(s)
Kinetic Capsule(s) Completed
That is what consistency would look like on the profile if you keep (s). While we're at it, let's just go through every other stat. Hack(s), Resonator(s) Deployed, Portal(s) Captured, Mind Unit(s) Captured, etc. It would be absurd to add (s) to all those stats just because there might be agents out there that only have "1" for that stat.
While I agree it would be simpler to say:
Mission Days Attended: 1
it's not exactly something that's going to keep me up at night.
And Intel Ops MIssions would be Intel Ops Mission(s). The "Ops" is always plural because an event contains multiple activities.
I have a feeling they might have trademarked "Mission Day" and "NL-1331 Meetup" or kept that clarity when translated to different languages.
