Welcome to Thunders, Keno & confab!
Keno, an inch in a year is possible, but don’t overdo it and break your bone trying for the big gains. Slow & steady: guys like P9 have been at this for more than 20 years.
confab, this site is a treasure trove of information on PE and all kinds of other topics as well. Try starting here. Oh, and confab, please use standard English when posting: following the rules of grammar and using spell check really helps to make posts easier to read.
