Average Trade Length, etc


I found something weird in my trading system(Option Leverage):

1. The average trade length is 472.7 days but this system was created only 5 weeks ago.

2. P/L per unit is negative ($2.15) but the annualized return is 629.17%. How come? I think the P/L per unit calculation is wrong.

3. Collective2 Ratings search shows no result by entering the system ID 14322476 or my name. The search was ok a couple of weeks ago.
