WP:GRFA is an ongoing effort by at least eight users. There might be more at this point. It first developed a few days ago, and has been under development since. It's not 'final' yet (nor should it ever really be), and so it's not been linked into WP:RFA and associated pages. However, as you note, it does carry significant material advice to potential administrator nominees. I've used it a couple of times so far in directing people. So far, it's been received well. I guess that's the beta test ) With regards to self nom; I recommend that someone else nominate you. I've been keeping track of RfA statistics since late June. There have been 144 non-self nominations for users with more than 2,000 edits*. There have been 38 self-noms. The success rate of non-self noms is 83%. For self noms, it's 68%, a 15% difference. If you want me to nominate you, I'd be willing to consider you against . My standards to nominate are possibly the strictest around. First, you need to clear 3,000 edits. Note that those standards are for me to nominate; they do not affect how I vote on a nomination. Based on your average # of edits over the last 30 days, you should reach 3,000 edits by the end of this month. Your current average # of edits per day overall is 12.65. Over the last 30 days, it's been 33.76. 

* - I did  of 126 nominations from late June to mid-September. I found a glaring difference in the success of nominees with <2000 edits vs. >2000 edits. That's why I limited my success comparison of self/non-self noms to users with >2000 edits, as <2000 edits is a different case. 

All the best,
