Sure, but in theory one could now have one very big, profitable day with a trade open for many hours, and 9 days of scalp-trades each losing a tick or two, and still qualify.
...and that's perfectly legitimate. Imagine a very high reward-risk system (i.e. 20:1) which also has a 10% win rate. You take a bunch of stop-losses and once in a while, there's a runner that covers them all and adds plenty of profits. Over 10 days, especially if it's a slow system (1-2 trades/day) it's entirely possible to have only one winning day and otherwise meet combine requirements.
And without going that extreme, basically the fewer trades a system yields per day, the longer the drawdowns, measured in days. Someone doing 20 trades a day shouldn't have a problem meeting the 45% of days, but that's not everyone.
