pathfinder 1e sheet for Kineticist elemental overload auto calc

I am trying to put a self-adjusting macro that based on my current burn gives bonus attributes to 2 stats (Con, Dex) I want to have the macro calc  if burn >=3  then attribute +2 , +2   I was working on the idea of using {0,-2+@{kineticistburn}}kh1 and somehow rounding down to either 0 or 1 *2 so the buff would be either 0 or 2 having a similar buff for when burn => 5 and so on. which gives more stats  +2 (total +4,+2) I know I can just create a buff that just is +2 to 2 stats and turn it off and on but why do things the simple way when you can make it more complicated so that I don't forget to turn on or off.     if this is the wrong place to post such questions I apologize and let me know where I should have posted. 

I found a workable buff calculation  for 3 burn {1,{0,(-2+@{kineticistburn})}kh1}kl1*2    (Con & dex)  (2,2) and 5 burn   effecting con again and str {1,{0,(-4+@{kineticistburn})}kh1}kl1*2 with above would be Con,dex,str of 4,2,2
