I posted a hand a few days ago where i made a shove completely out of the range i should be shoving in that particularly spot.
Some people comment about it, and the nash shoving chart came to discussion. Where can I find a good shoving chart? I searched online for the nash HU shoving chart, but didnt really understood how can i put it to use on a 6max/9max mtt table. Honestly, didnt even understood it at all. All my shoving ranges in sng´s (I play 6 max) come from cEV calculations and SNG wizard.
I´ve been watching Tony Guerra´s series and i´ve been doing some calculations about certain shoving/calling spots that i face on my day to day game in order to improve some leaks i feel i really need to take care off.
I feel like i´ve been playing pretty decent in lots of aspects, but i dont feel like a have a good enough edge on regs when it comes to open shoving 8-13bb. Sometimes i feel like im shoving waaay to wide, sometimes I feel like i didnt shove on a pretty decent spot. (Usually I err on the side of shoving - When Im 50/50 about shoving or folding, gl me)
I was thinking about calculating shoving spots from any position in the table according to several shoving stack sizes, in order to make my own shoving chart.
Is anyone out there who has already done this? Is there a good shoving chart that I can look at, run some math to see if the chart is good, so I can save some work?
I would really appreciate somebody sending me a chart, giving some advice about how to do it quickly.

Ps: Im Portuguese, just ignore some grammatical leaks.
