Firstly thanks for the valuable ideas.
For item 8.5.1, seems that there are different viewpoints regarding this one. However, having a more careful look at item 10.5.10, penalty of ‘match disqualification’ will be incur if failure to keep finger out of the trigger guard during movement’. So, I tend to believe that it is not a ‘must’ to engage any safety as there is no penalty clause for not doing that.
A new related question, does anyone know what exactly is ‘taking more than one step’? E.g. 2 feet on the floor, when one of the feet lifts up and steps down to the floor (that is one step), another foot now lifts up and starts moving but not yet steps down to the floor – is this ‘taking more than one step’? Or this should apply only if this foot has also stepped down to the floor?
For item 9.1.5.3 & 9.1.5.4 – understand the situation now. Thanks.
A new related general question, a paper scoring target with broken outer perforation should be counted as a ‘Delta’, correct?
