[1] For years, Stompé was considered the third best Dutch darts player behind Raymond van Barneveld and Roland Scholten.

Stompé came back to fame with the defeat of reigning BDO champion Jelle Klaasen in the first round of the 2007 World Championship.

He then suffered first round losses in the World Matchplay to Adrian Lewis and in the European Championship to Gary Anderson and also went out at the group stage of the Grand Slam of Darts.

He then reached the quarter finals of the 2010 World Matchplay, defeating Andy Hamilton and Mark Webster before losing to Raymond van Barneveld.

In December, he partnered van Barneveld in the Netherlands team which won the inaugural PDC World Cup of Darts.

[3] He was bitten by a dog over the Christmas period and couldn't replicate the form he showed days earlier as he lost 1–4 in the second round to Terry Jenkins, hitting just 28% of his doubles.

[4] 2012 proved to be a disappointing year for Stompé as he could not reach a single quarter-final out of the 25 tournaments he played, with his best finishes being last 16 defeats in Pro Tour events.

[5] Stompé dropped out of the top 32 during 2012, but qualified for the 2013 World Championship by finishing fifth on the European Order of Merit, taking the first of four spots for non-qualified players.

Stompé's son, also called Co (born 1991), plays on the PDC Youth Tour, and reached the final of an event in Crawley in May 2011.

The court in Almelo considered forgery of documents and the deliberate submission of incorrect declarations for turnover and income tax for the years 2009 through 2013 to have been proven.
