First, I used GWM as the best intermediary to compare GJ and YG, becuz GJ and YG both fought with him. And GWN and GJ during Hero'sFeast is the best place to start cuz that is their earliest match and they are roughly equal.

So GJ=GWM=100 (innerPower point). It doesnt matter if its 50 or 100 but a higher number (but not too low and not too high) ensures a "good estimate" later on. [from Physics class.]

Then I take their total_innerPower up to that point ( 100 ) and divided their ages to get an average_innerPower_rate at that point in time. So, 100/33. GJ "cannot" be age33 or younger becuz he practiced 9Yin for 20years, making his first practice to be at age13. However, I'm giving GJ a better rate to make YG look bad. Also, becuz Superboy doesnt believe in "natural (logarithmic) functions," I continue to use slopes [besides, I dont like calculating log ftns]. Another reason is GJ's QZ and 9Yin has a constant growth rate.

To get GJ's innerPower after 16years, GJ_innerPower_rate x (4years to start 16year separation) and add this with GJ_innerPower_rate x 16years. Then add 100 (initial innerPower).

Now, we want YG's average_innerPower_rate. The best place to compare YG's innerPoewr is the GWM vs. YG at QZ Palace, where YG is "almost" tied in innerPower with GWM. And note, YG during his first year out of the 16 years also improved his innerPower (it's mentioned twice, so I believe he should reached GWM's innerPower at QZ Palace). [note: It doesnt matter if we set YG's innerPower to 100.]

YG in the first of 16year separation is around 21-22 (I used 22 to make YG look bad.) GWM's innerPower_at_QZ_Palace divide age22 to get YG's average_innerPower_rate at that point in time.

To get YG's innerPower after 16years, YG_innerPower_rate x (16yrs - 1) and add GWM's InnerPower_at_QZ_Palace. However, this innerPower is if YG continues to practice DGQB's stuff and we only read YG's first 7 out of 16 years. So, this is YG's innerPower_max.

To get YG's innerPower_minimum, YG_innerPower_rate x (7yrs - 1) and add this with GWM's_innerPower_rate x (16yrs - 7). And add GWM's innerPower_at_QZ_Palace to get YG's innerPower_minimum. [Note1: GWM's innerPower_rate is 100 divide GWM'sAge_At_Hero'sFeast, which is 20 years older than GJ: 33 + 20 = 53][Note2: GWM trained "harder" during the 16years, so this rate is actually crappy but I used this for YG's minimum_innerPower_rate.]
