Crafting Recipe loop... is this good practice or not?

I am thinking about coding crafting recipes that allow Items to be crafted with damaged materials, however the materials can't be pass a point of damage.

Is it ok if I code this as a crafting recipe loop?

		for (int counter = 0; counter <= 20; ++counter)
	{
		GameRegistry.addShapelessRecipe(new ItemStack(mod_HarkenScythe.HSTalisman, 1, 1), new Object[]
		{
			new ItemStack(mod_HarkenScythe.HSTalisman), new ItemStack(mod_HarkenScythe.HSSoulVessel, 1, counter)
		});
	}

Simply states that the new Item HSTalisman can be crafted with any HSSoulVessel that is not damaged beyond 20.

Would that cause problems for such mods as NEI or add unnecessary recipes into the memory?

I have about 5 other items that would use this loop, and each will have a 40 damage limit loop too.

That is about 300+ recipes......
