The error occurs when a player's name is changed
AND the player changes sides during the same season. It is not obvious in BowlsLink player ladders or results that it is the same person who has played in multiple sides. An example of this would be William Wonka who had the diminutive name of Willie which was then changed to willie. He would be shown as both William (willie) and William (Willie) Wonka. In this database there are 791 instances where the player's name has been duplicated except that the name within brackets has 1 or more of the letters in upper case. Some halfwit behind BowlsLink is actually the cause of this as some time during 2021 the diminutive names/nicknames of
ALL players were changed automatically.
Equating William (willie) and William (Willie) Wonka is easily done (and this program does it) but a change of name from, say, Susan Jones to Sue Smith would not be obvious.
