Success rate script - Now updated for new delete terminology since v1.29.3

@BrightSilence I use excerpts from your script for my monitoring script. However, these specific audit alerts are incorrectly classified as critical and not, and I agree with you, only as a warning or notice. Therefore I would like to specify this in my script - but this does not require any change in the success rate script. I absolutely agree. Thanks for your support and feedback. @SGC @Toyoo
