This is one of my personal best gain years. I had a "spurt" a few months back where I got a wild hair up my ass and was hanging a total of 4 hours a day, 6 days a week...I gained 3/4" in about 2.5 months time. I'm hoping to make it a total gain of over an inch this year. It's not impossible to gain over an inch a year. I see a lot of guys with very low goals...it's like they think it's impossible to gain more than an inch a year or something. I'm not bragging, I think others have done better than me. I dont know for sure who's supposedly had the best gains in a year though. At my current pace I expect to gain at worst another 3/8" between now and December and at best another 3/4". We'll see.
