You could if you want to, and I say, why not? Would you happen to be boiling less than the recipe states, and topping off later? Is the alpha acid percentage of your hops lower than the recipe states? Adding more hops can help for better hop utilization in small boils and bring a low AA% hop to the right IBUs for the beer style.
Chances are, I don't think you will notice much from .25 oz.

It's less than 10% difference; That's probably less than:
- The AA loss from keeping them in the fridge for 6 months
- The difference between using leaf vs. pellet.
- The difference between using full vs. partial boil.
- The difference between rolling boil vs. simmer.
- The IBU difference between Rager/Tinseth/Garetz.
This hobby has a lot of variations, which result in many different beers from the same identical recipe; 10% will not be noticeable.
Just use them. Seems pointless saving 0.25 ozs.
If you are really concerned that it will upset the bittering balance (which it will not), you could just toss the extra 0.25 ozs in at the end to get a hint of aroma.
