Welcome aboard! You will certainly have a fine moustache, however, it seems to me that you never should have pushed them to define "closely groomed". A 1 inch beard can easily seem "closely groomed" if you are good about snipping away the flyaway hairs. The people who decided on a quarter inch likely had nothing on which to found that number other than it seems nice and short. In truth, the neatest looking short beards are always longer than that. At a quarter inch, it doesn't look like much more than ungroomed stubble...

I look forward to seeing your moustache grow

Stop trimming your moustache; greater glory awaits!
...but if you are going to trim, do it right, go pencil...
...then, of course, a nice copstache can be cool too...
