The time in seconds, until a „Enter captcha“ dialog disapears.
If checked, the automatic captcha recognition is disabled globally.
Jdownloader's anti captcha module calculates a value that says how „sure“ JAC. This value is the so called „vality value“
0 --> probably wrong detected 100 --> absolutly correct
If JAC is unsure about the result (low vality value), it shows a captcha dialog to enable the user to edit it.
By default, the treshhold is set to 80. This means, that JD shows a captcha dialog if the „Vality value“ is below 80.
