All time - In your profile you will see something like you have 200 MHOs out of 1,000 (20%) That means of all the opinions you have given MHOs were awarded on 1,000 of them of which you got 200 - Does that make sense?
Hi! MHO% is the ratio of the number of your opinions that are selected as Most Helpful Opinion, to the total number of your eligible opinions (your eligible opinions are the opinions you posted for questions that has MHO selected for your gender after you post your opinion). Your MHO% can fluctuate often depending on how many opinions you are posting and how often your opinions are being selected as Most Helpful. This information can also be found in our FAQ here. :) http://www.girlsaskguys.com/faq#196
