Color is usually some shade of yellow and often varies with the concentration of the sample. The most common color descriptions of normal urine are straw, light yellow, yellow and dark yellow. Amber colored urine is seen in patients with increased bilirubin levels and may indicate hepatitis.
Add the knowledge of bowling's perfect score, 300, and it stands to reason 10 strikes in a row is a perfect 300.
Since score is not an issue when you practice, it is certainly useful to train your physical game elements in your outline regardless if you have a full set of pins standing or if only a few are standing. Each game of bowling has 10 frames with the final frame allowing for an additional delivery. If you do not try to roll a strike when a full rack of pins are standing, then you should be able to get 20 deliveries per game of practice to work on your outline training components.
