Unfortunately with our long formats, we dont necessarily see pattern carving by design, but more by the lack of knowledge of tournament bowlers. With such a variety of styles on the right hand side of the lane, we are our own worst enemy, some more so than others at times, when the condition opens up in our favour we are unstoppable, but it rarely happens anymore with asymmetrical patterns.
The last two national tournaments have shown how much of a difference occurs when bowlers with particular similar styles have shots concentrated in a similar part of the lane. It was quite noticeable in the QLD Cup the effect the women had on how the lanes played, where the majority of them bowled around the 8-12brd mark wearing out the traditional track area of the centre. This basically screwed the shot on the right for the back half of the day, creating massive over under reaction forcing the men to move inside on lanes that have quite a noticeable reduction in carry potential once you move left inside the normal track area.
A similar occurance happened with the combined qualifying for the Australian Open, it just depended on who you followed to the next pair and what squad you bowled in. Almost thought the right hand side might have been alright for the matchplay when the fields seperated but they trashed out again because 1 bowler decided to use a dull high end ball in the track area for most of the day, again screwing the ideal shot for the majority.
