It is always funny to read stuff denigrating people who can't run a five-pack or better. Strangely enough, apart from pros, I have never seen people run five packs on 9 footers in any club or local pool hall, ever. Well, depends on what you consider to be a five-pack. If you have to pick up from your opponent twice or 3x per game, well - if it means running all (at least) 9 ball-racks five times consecutively without your opponent at the table at any time in between - I think there is a lot of bragging involved on the internet.
Even with pros below the top 20 you rarely see -real- five packs in tournaments. So, pretending that five packs are a measure of knowing how to play pool is pretty ridiculous. Yep, some people have achieved them in practice or maybe even once in a tournament somewhere (possibly on a barbox) but that does not mean that they are top notch pool players. I agree with the poster above that every time I heard stuff like that from people and met them in real life they either got beaten by me or unconvincingly beat me. Light years away from five packs.
And I never claimed to have run a real five pack. The few really non-pro but excellent players I know never ran a five pack on me yet but I do believe they might have run a few in their life. Pretending that a five pack is anywhere near normal and a sign of a worthy pool player is too ridiculous to believe.
If you really are a "five pack player" you should be giving me the last 5 and beat me in a race to 5 easily. Even if it is not your 5-pack day. I have yet to meet such people - real pros not included.
