In tournament play, the game starts you at Level 1, which gives you the lowest(worst) attribute levels for power, skill and caddy. If you do well in tournaments, the game will increase your overall level for later tournaments, which increases your power, skill and caddy levels. Level-warping ARNIE Codes 20 thru 30 automatically give you the power, skill and caddy levels of the level you choose. Since you can normally set your overall level in practice rounds, these codes are good only for tournament play. The following chart shows power, skill and caddy levels in relation to overall level: (chart is currently missing, if I happen to find it, I'll post it)
Finally, Codes 31 and 32 have no benefit in practice rounds, since there are computer opponents only in tournament play.
