NIFTY BANK Vs PSU Bank Vs Private Bank

I was wondering who is pushing the Bank Nifty so I decided to visualize this by this simple comparison.
The three major PSU banks are compared with the NIFTY BANK there market cap is as follow

3 (25%) PSU banks out of 12 holds 28.05186836 % of NIFTY BANK VALUE.
9 (75%) Private banks out of 12 holds 71.94813164 % of NIFTY BANK.

(YoY) in % YTD in % 30 mar to 18 Nov in %

BANK NIFTY -5.56 -8.14 57.31

PSU BANK* -41.95 -43.64 6.03
State Bank Of India(L) -25.47 -26.3 31.7
Punjab National Bank(L) -49.1 -52.8 -7.29
Bank Of Baroda(L) -51.28 -51.82 -6.32

PRIVATE BANK** -17.32 -19.41 62.00
INDUSINDBK -42.02 -45.4 96.12
AXISBANK -13.6 -15.58 72.68
ICICIBANK -1.29 -8.21 56.2
HDFCBANK 11.16 9.92 68.91

*Average of PSU banks included in NIFTY BANK only
** Average of Private banks included in NIFTY BANK only
(YoY) in % YTD in % 30 mar to 18 Nov in %
BANK NIFTY -5.56 -8.14 57.31
PRIVATE BANK** -17.32 -19.41 62.00
PSU BANK* -41.95 -43.64 6.03
Where BANK NIFTY is down by 5.5% PSU BANK* is down by 41.9% on YoY basis.
After 30 march 2020 where BANK NIFTY is up by 57.3% PSU BANK* is only up by 6% even though PSU banks holds 28.05186836 % of NIFTY BANK VALUE.

It is interesting to see that after 30 march 2020 ,the 28.05 %(%value in Bank Nifty) of 57.3 is 16.7 that means PSU BANKS** contribution in Bank Nifty is lagging by (16.7-6=10.7)10.7%
It is interesting to see that after 30 march 2020 ,the 71.94 %(%value in Bank Nifty ) of 57.3 is 41.24 that means Private BANKS** contribution in Bank Nifty is leading by(62-41.24=20.76) 20.76%

With the above observation it is clear that at least PSU banks included in NIFTY BANK are the ultimate underperformers and the move of NIFTY BANK is solely because of the Private banks in NIFTY BANK in the last two years
Data Taken from nseindia official website.
Let me now what's your take on the above observation in comments and also comment about such bad performance of PSU banks.
