norisk, what you've described is essentially the same process i'm following now. I use a spreadsheet to complete my ratings, use some really simple filters to improve the results (i.e. Don't bet country QLD, Don't touch Slow/Heavy tracks etcetc) and away I go. I then base my staking on overlays and thats my process.

Is this a system, strictly speaking probably not but i classify it as my process/system.

Personally i've only started participating in this forum over the last 1-2 months and I've found the discussion in a vast majority of threads to be helpful and that most people genuinely want to help each other. That doesn't mean giving away the keys to the kingdom as some people here expect (for some reason?) but if you were to put every bit of pure gold hidden in some of these thread's into a notebook and utilised it, I feel you'd be hansomely surprised.

People here aren't going to give you the answers on a platter but without the comments from people like AngryPixie, TheSchmile, Shaun (A+), garyf and a few others that I can't name off the top of my head, i'd be completely lost. However taking snippets from the insight that each of them have given has enabled me to find an approach that works for me and is to date (even though its a small sample time) is working profitably.

Even people like moeee who I haven't had run ins with myself but know his type, can sometimes express their opinion abruptly, but they opinions are still valuable even if they go against the grain of the majority. Actually in these circumstances sometimes they are even more valuable.

Anyhow enough rambling, I feel some of the discussion around here since i've been a part of the forums has been fantastic. Sometimes it can take some reading but i've found its well worth it.
