Here's a pitcher of some coffee beans. In this pic you'll find a man.
The test is in how long it takes you to find him. Yes he realy is there. It's not a trick.
3 to 30 seconds is strong.
1 min is still good but a tad bit weak.
Between 1 & 3 min shows room for improvement.
Over 3 min & you need to work your mind more to get it to where it should be.
