Based on the given sentence above, the complete action verb would be "should have been training". When we say action verb, this is the type of verb that serves as the main verb in the sentence for it tells what the subject is doing or what the subject is all about. This is the complete action verb because the tense is included to make the verb understandable as to when the action actually happened.
Answer: Disagree
Almost every situation has different environments, situations, and circumstances. While there is a possibility of replicating success through repetition, this is very unlikely. In most cases, an outside factor will change the results and cause a different outcome. It honestly depends on the situation and environmental factors, but it is not to say that this is completely impossible.
I hope this helps. Have a nice day :)
