All played boxed/straight - perfect result. Excellent end of a Friday the 13th. Download it and check it yourself!.
As of the question concerning the 3 hot, 3 cold. My opinion and of course intregrated into Fire & Ice. is the following.
More cold numbers than hot numbers. I worked on that for a long time and it is used to a certain extent in all of my tools. For a decent priced wheel 2 hot / 5 cold is perfect., 3 hot / 6 cold better than 2 / 8, lowest option in my opinion 2 hot / 3 cold. Never equal hot/cold, always more cold than hot.
Let a program decide the hot and cold numbers. And give it enough numbers to decide. With the five numbers you showed there is no distinction between the 7 and the 2 - other than that the 2 came more recently - which does not necessarily make it a better hot number.
If you take a pool of the last ten draws it should not matter which one of the numbers came more or less recent. It should be dventually stirctly on how often the numbers appear and some side effects. Why? If these 10 numbers arr your "sample" from which you want to make future assumptions, they should all have the same "value". That's what I found out and that's what I use, and that's what I play and what - at least sometimes - apparently works.
