I found a Tears Up pill and copied it a whole bunch of times with Jera + Blank Card. After eating an entire double room of pills, my Tears stat is only at 3 and Isaac is not visibly firing faster.
Is this supposed to happen?

There is a ceiling value for your base tear rate, but this can be modified by what items you pick up. Eve's Mascara, Polyphemus, The Inner Eye, and Mutant Spider will reduce your tear rate by a given modifier. Your rate of tears is dependent both on your base rate and the modifier.
Also, the tears stat is a bit odd in that maxing it out through normal means will not show up as a maxed stat on the stats screen. The only way to get that max level tears stat is through Soy Milk, but that massive damage reduction doesn't usually make that worth it.
Generally speaking you shouldn't count on the stat screen to be perfectly accurate.
