Loom vs Projectile Arrow Cal

This is a game of Loom-mouse recognize.The functions are: 1.Count all the Designated item.Then add the middle two numbers.What is the final result? 2.According to the requirements, may I ask what the value of the question mark should be?

This is a computing application designed specifically for shooting accuracy, compound bow hunting, and archery enthusiasts. We transform complex physical parabolic formulas and equipment mechanics models into intuitive and hardcore tactical dashboards. Whether it's adjusting the sight to zero or assembling a dozen new arrows, we can provide you with precise data support. 1. Tactical ballistic calculation Accurate calculation: Input the initial velocity (FPS), weight (Grains), and target distance of the arrow to instantly calculate vertical drop compensation (Drop) and horizontal wind drift correction (Wind Drift). Environmental adaptation: Supports setting of crosswind speed and direction parameters 2. Arrow calibration analysis Momentum and F.O.C.: By comprehensively calculating the intercept length, rod to weight ratio (GPI), arrow and tail feather accessory weight, the total weight of the arrow support, momentum factor, and F.O.C. (center of gravity forward displacement rate) can be accurately obtained. Equipment matching: Visualize the center of gravity position to assist you in determining whether the spine hardness matches the current weight, optimizing flight stability. 3. Score prediction Based on your average single arrow and number of arrows, calculate the total score of intelligent calculation theory. Status assessment: Provide competitive status ratings to help shooters establish reasonable psychological expectations and goals before competitions and assessments.
