don't understand... are you trying to figure out if the volatility of the p+l is in line with the size of vega ?

Sorry I am not clear in my question. I calculated the standard deviation of vega pnl in relation to historical vol move. From here how do I conclude whether the vega position is in the right size or too large. Thank you.

How about checking your risk limits, stop loss or similar?
