What is considered a low sensitivity?
And to give you an idea, a sensitivity rating of 86dB (decibels) is considered relatively low, while anything above 110dB is on the high end.
~400 and 2 is a good medium range sensitivity. 1.5-2 is like a medium slow. <1.5 is considered slow. 2-2.5 is like a medium fast then >2.5 is fast in most peoples cases. I am giving these examples as if everyone played at 400 dpi.
The average sensitivity of a Boolean circuit is the expected number of input bits that, when flipped, change the output of the circuit, starting with a random input setting.
Sensitivity refers to a test's ability to designate an individual with disease as positive. A highly sensitive test means that there are few false negative results, and thus fewer cases of disease are missed.
The test is perfect for positive individuals when sensitivity is 1, equivalent to a random draw when sensitivity is 0.5. If it is below 0.5, the test is counter-performing, and it would be useful to reverse the rule so that sensitivity is higher than 0.5 (provided that this does not affect the specificity).
A test with 80% sensitivity detects 80% of patients with the disease (true positives) but 20% with the disease go undetected (false negatives). A high sensitivity is clearly important where the test is used to identify a serious but treatable disease (e.g. cervical cancer).
Pro players use lower Valorant sensitivity settings because the wrist is far less accurate than the whole arm. Lower sensitivities allow you to use your whole arm and make more extensive and more comfortable strokes at higher accuracy.
What is the correct mouse sensitivity? There isn't a specific mouse sensitivity that works for all people, it's mostly a matter of personal preference. Set the in-game sensitivity to 1.0 or as low as it is possible and increase your DPI settings for better cursor performance. Some of the best CS players stick to 400.
At a DPI of 800 your mouse will 'measure' 800 points of movement per inch that you move your mouse; at 1600 DPI it will measure 1600 points of movement per inch, making the cursor on screen move further with less movement as a result.
For a test to be useful, sensitivity+specificity should be at least 1.5 (halfway between 1, which is useless, and 2, which is perfect). Prevalence critically affects predictive values. The lower the pretest probability of a condition, the lower the predictive values.
What is a low sensitivity pregnancy test?
High sensitivity pregnancy tests can detect hCG levels as low as 25 mIU/ml, and low-sensitivity pregnancy tests can detect hCG levels as low as 1500-2000 mIU/ml.
Sensitivity level is an indication of how sensitive the data in a project, table, or column is. Data is sensitive if it contains detected elements, such as personally identifiable information (PII), financial data, and credentials. A data profile can have any of the following sensitivity levels: High.

A test that is 100% sensitive means all diseased individuals are correctly identified as diseased i.e. there are no false negatives. Importantly, as the calculation involves all patients with the disease, it is not affected by the prevalence of the disease.
