Add AvgROI%, as counted by SharkScope

Hi,
I have a request for useful stat "BI_ROI%". Nowadays its counted by SharkScope, but not PT4.
===
In PT4, ROI% is shown as = My_C_Net_Won / My_C_Buyin
However, playing different buyin levels, this approach are not enough to measure the skill.
Let's use kraada's example https://www.pokertracker.com/forums/viewtopic.php?f=59&t=37415&p=187202&hilit=roi#p189902
In average,
- win for each $10 tourney is $50/10=$5. ROI% is $5/$10=50%
- win for each $1 tourney is $20/10=$2. ROI% is $2/$1=200%
PT4 would count Avg ROI% as (50+20)/(10*10+1*10)=63.63%.
Sharkscope would count it (let's define it "BI ROI%") as (($50/$10+$20/$1))/(10+10)=125%, because 25 buyins has been won in 20 tourneys.
125% is non-weighted average between 50% and 200%, and tells mostly about overall player's skills in this structure, no matter of buyin amount.
63.63% is weighted average between 50% with weight $10 and 200% with weight $1. It always be close to ROI of highest level, and tells mostly about cashflow and skills on highest buyin level.
So, these two values are both useful, and should be shown together in "View Stats/T/Results/Tournament/Overview", like
ROI%=63.63%
BI_ROI%=125%

You play 10 $1 tournaments and win $20.
Does this mean at the end of the graph you would have shown as +25 buy-ins? (50 / 10 + 20 / 1 = 5 + 20 = 25)
In average,
- win for each $10 tourney is $50/10=$5. ROI% is $5/$10=50%
- win for each $1 tourney is $20/10=$2. ROI% is $2/$1=200%
