Τηε only way to have a subjective realistic ranking is to follow what was recorded in FIFA ranking since its creation.
Ιt is not perfect, but will be close to reality.
Ιn order to produce a better & more accurate rating I added some variations for each continent to balance some continent nations can score more points given how easy it is. Therefore the data had been correlated with slight tweak in algorithm for those 4 categories of continents : South America, Europe, Africa and rest of world to take into account how hard is each continent.
Τo create same balance as FM, we fixed some values of some countries between to keep values closer to what FM wanted overall.
here is current top 35 team..
Republic of Ireland 126
Côte d'Ivoire 124
Σome may say but this country is now better than X country etc, but the fact is this changes over time. Not long time ago Bulgaria had a decent team, same for Romania, but that has changed. The realistic approach is to take overall time not precise time. Let us take Holland for example, some years they are best country in world, some years now they are below average.
