Personal Portfolio Returns on Resume

I manage a personal portfolio that is very concentrated and it is not levered. It has outperformed the S&P 500 by about 180% since its inception with purely long equity plays. Is this figure worth including anywhere on my resume? So far, I've just told interviewers that I've done pretty well, but I haven't let on the magnitude of my performance because I feel that luck (as with most investments) has been a big factor in my success.
