Finally got an answer that actually replied to the questions I asked. Apparently there was a late scratching in the last in Adelaide and my 17.00 became 7.00 just like that. Must've been 10/1 on or something, the late scratching. All these rules and regulations that cause you to get less than you think you should.... Reminds me of my SP in the 60s who had a 5/1 limit. Don't know what became of him. Maybe he went on to become a listed company.
