EDIT: Hmm... I didn't see Darkflagrance's post. But either way, my points below still hold. So this isn't directed to you Mekkah, but anyone who wants to know the difference between attack calculators and this chart.

For calculating a single pokemon, probably. But there are key differences:
1. Damage calculators are more precise, giving precise % points where someone would be killed or whatnot. Whereas these attack tiers simply give a figure of who is OHKOed, Two Hit KOed, etc. etc. (Granted, there is a simple formula to convert the approxamate damage difference into an approxamate % value... but you'll require a calculator for that. The attack/defense tiers can all be done easily within your head)
2. The Tier lists are easily modified. Multiplications have been transformed into additions. Whereas mutliplying 55% to 65% damage by 1.5 is difficult to do in someone's head (to see what happens when guts is activated)... or hell, what happens when Life Orb is on the pokemon (multiply by 1.3), you can very easily just add
4.25 to the attack tier and compare the new difference.
Super effective? No need to multiply, just add 7.27.
3. Whereas an Attack Calculator you need to know the defending and attacking pokemon in advance (to plug in the numbers or in MetalKid's calculator... you need to select them from a list), the Defense Tiers allow you to compare pokemon you've never considered before.
EDIT: Oh, and finally: be free to round. There are 2 decimal places because that is when things get absurdly accurate (I'm talking like 0.1% here). But taking it to 1 decimal place will give you an error margin of only 1%, and rounding to a whole number gives you an error margin of 10%.
Explosion's base power is effectively around 500 because it halves the opponent's Defense immediately before doing damage. Other than that, this is some very nice work.
I see. But that is easily simulated adding 7.27 to the attack tier (or subtracting 7.27 from their defense tier) :-) I'll edit that note in however.
