She was questioned further. She said that maybe 15 times she would pick up the maximum and the remaining 20 times a couple of 1.7's. Under further questioning, she said that the lowest could have been an ounce but that she was guessing. She later agreed that the minimum in a week would have been one ounce. That would have occurred in more than one week but she could not tell exactly. She said she did not know the exact amount. Pressed further for more precise evidence about amounts and times, she did not give it. She denied that the 2.5 figure in her statement was a complete guess; she had picked up knowledge of the cost. Under further cross-examination she accepted the proposition that four of the weeks were only about one ounce and three weeks were more than one ounce and she was relatively sure that one of the three weeks was 2.5 ounces - but she was going on the money being talked about. She repeated that she could not be sure, that she was only going on the size of the blocks and never weighed them herself. She said that what she said she believed to be true but she couldn't dispute the suggestion that the weight could have been less than 2.5 ounces, 2 ounces or less than ½ ounce, but she thought the latter was getting "sort of unlikely". In the end she accepted propositions put to her by counsel for Ms Simonds that her best estimate was that there were four weeks where she collected one ounce a week, three weeks where she thought she would have picked up at least 1.5 ounces and that beyond that she was guessing. In re-examination, counsel for the Crown questioned her about the money she was given for the task. She agreed that she was paying $2,400 when she went over there but could not say that that occurred every time. She said she went with a satchel with the money in it and the drugs would go into the satchel. She said she did not count the money every time and it wasn't the same amount every time - something she could tell from the thickness. There was further vague evidence on the issue. I turn to the submission on this appeal.
