Is Shimada Hanzo's archery posture really feasible?

The bow-"Feng"-is very handsome, and Blizzard has done a good job in the details of the bow and archery. I think either Blizzard has studied relevant knowledge or the producers have archery enthusiasts. One thing must be explained first, when pulling the bow, the bow should be erected. However, considering the gameplay, if Shimada Hanzo pulls the bow vertically, the first-person perspective is too uncomfortable, so he changes to sideways. We can see teammate or enemy Shimada Hanzo pulling the bow vertically. Although Shimada Hanzo is Japanese, his bow is not a peace bow, and Shimada Hanzo's archery is not a Japanese bow. And Mrs. Gong are too heavy to be used in street fighting in Yuto. The landlord thinks this bow is an American hunting bow, while Shimada Hanzo's archery is a standard Mediterranean shooting. At present, there are two main archery methods, the Mediterranean shooting in the west and the Mongolian shooting in the east. Shimada Hanzo used the Mediterranean shooting method, which is typical: when pulling the bow, use the index finger, middle finger and ring finger to pull the string, and the index finger and middle finger hold the arrow (but don't touch the arrow or lightly touch the arrow); The arrow is on the inside of the bow (for example, if you pull the bow with your right hand, the arrow should be on the left side of the bow); When the bow is full, the right hand is close to the cheek or chin. We can see that Shimada Hanzo's action essentials are very accurate, except that he should hook the string with three fingers, while Shimada Hanzo only used two fingers, which is quite strange. In addition, there are these details: the arrow must have three tail feathers, and after taking the arrow, there must be one tail feather (the main feather) perpendicular to the bow drawing direction (see figure). This is what we saw when Shimada Hanzo was shooting an arrow. If you don't shoot an arrow with Shimada Hanzo, after about 0.3 seconds, you will find that Shimada Hanzo's hand is obviously shaking! This is very realistic. Bowing is a very energy-consuming action. If you don't shoot an arrow for a long time, anyone will have different degrees of arm jitter. Therefore, the coach of the Archery always asks us to shoot an arrow after pulling the bow, so don't hesitate, otherwise our hands will be even more inaccurate when shaking.
