I was looking for trends in the dates, and what numbers fell on certain dates. So, theoretically, you could reduce to the fact that the 279 digits come out on those dates, but the 9's are missing in all three of those draws. So you could assume that 99 pair would show. You'd play 99 pair until it hit, which happened to be June 10th...
I wouldn't have chosen 99 pair since it just showed in the evening once already last week, but the analysis of the relevant dates and number combinations is interesting, and quite fascinating. But it you look at it from a "facts" perspective from the pattern 297... the 9's are missing based on the trend.
If you really got into it, and abandon most other methods (except for detailed tracking), I could see it being effective. But you still have to keep in mind: repeating pairs, due pairs, longest out digits. You would really have to keep detailed notes and study it daily. It's so easy to forget that ONE number or that ONE pair that you've been after... and when it doesn't show for a little while, it seems to go by the wayside. You forget about it, and BAM, it hits when you least expect it. Well, that's what happens to me anyway
I'm fascinated by the trends, and how the pieces fit together.
I was trying to figure out possible pairs earlier, in relation to the date: 15... 5209 pattern ( I got fixated on that because of the 15th = 5)
The mirror showed midday 475... 920
