-     * <p>Let's say the {@code maxSpansPerRow} is set to 6. Widgets can be grouped in the same row

-     * should be moved to a new row.
-     * Example 3: Row 1: 6x4. This is okay because this is the only item in the row.
+     * <p>Let's say the {@code rowPx} is set to 600 and we have 5 widgets. Widgets can be grouped

+     * Example 1: Row 1: 200x200, 200x300, 100x100. Average horizontal pixels is 200 and no widgets
+     * exceed that width. This is okay.
+     * Example 2: Row 1: 200x200, 400x300, 100x100. Average horizontal pixels is 200 and one widget
+     * exceed that width. This is not allowed.
