In the special event, I have at times gotten lesser than the specified amount. for example in the ric flair last node it states that 200 event credits... But i have gotten 125 in some attempts..
Also the daily event clearly states 350 trainers and 4k cash... generally pulling 300 and 2k cash..
Its nowhere specified that it is upto. Also the rewards that are flagged as guaranteed, Only item type is guaranteed and not the amounts
Please look into this.
