annualized return wrong? revisit

[quant2008]

I have read #1433 and #1067
I tried the summation and exponential mode to caculate annualized return using #1433 method. and it seems both are wrong.

I ran workflowexample.ipynb, and I checked benchmark sh000300's annualized return from 2017-01-01 to 2022-10-30 given by qlib.
summation mode gives annualized_return 0.02904496924711926
exponential mode gives annualized_return 0.06986045104183725
while correct annualized_return given by QuantStats is 0.0117.

I wonder why?
