The values showcased above are all considered for the final GFP ranking recognized as the "Power Index" (abbrv: "PwrIndx"). PwrIndx scores are judged against a perfect value of "0.0000" which is realistically unattainable due to the number of factors considered per country. Balance is the key - a large, strong fighting force across land, sea and air backed by a resilient economy and defensible territory along with an efficient infrastructure - such qualities are those used to round out a particular nation's total fighting strength on paper; it is not enough to field 10 million men or 20,000 tanks or lead the world in oil production.
Each nation's final ranking also carries with it bonuses and penalties as needed while landlocked countries (ex: Austria) are not penalized for lack of a standing navy - though they do suffer a penalty for not maintaining a viable merchant marine force.
It bears repeating that nuclear weapons are NOT taken into account for this listing. Powers are based on conventional weaponry in inventory as well as other factors such as economic strength, border size, self-sustainability (in regards to wartime resources such as oil), water access etc...
