| + | For example you have max connection set to 1000 , and trigger sensitivity to 20, and currently you have 900 connection , so in that case | ||
| + | |||
| + | 900*100/1000 > 100 - 20 | ||
| + | |||
| + | 90 > 80 | ||
| + | |||
| + | so the incoming connection will get reCAPTCHA test. | ||
| + | |||
| + | and calculates backward , you will see that when connection is under 800, user won't hit reCAPTCHA test. | ||
