I missed your post Scottik, sorry.
The problem is that 1 regular level is
not equal to 1 regular level!
The power difference between level 164 and 165 is not the same as 165 to 166. The power difference between 206 and 207 is not the same between 207 and 208. Your chart does good at representing the difference between the
number of regular levels, but that's it. You don't buy a house based on the number of rooms without taking a look first. What you thought was a mansion may just turn out to be a closet. The IP you get from level 1->2 isn't the same as 150->151 either. IP cost between skill points isn't the same. Going from a lvl1 perk to a lvl2 perk isn't the same as going from lvl9 perk to a lvl10 perk.
Everything from breed caps, to TL caps, to equipment, to unlocked weapons, nanos, perks, to ip cost.. everything has to be taken into consideration. Basing it on the difference between levels has flaws, and accepting those flaws because it fits some mathematical formula is whack. The difference in regular levels is an indication of power, but it shouldn't be followed religiously to determine the ranges. Basing it on what risk people are willing to accept vs what they gain is a better indication of what's viable and what's not. Being subjective and looking at the power changing benchmarks is a better way of going about it, without ignoring what happens when you enter the SLs.
nerf, my last post is at the bottom of last page just like yours
