"It gives me confidence that with strong leadership from council, Aratoi can be put on the right track," Mr Goodwin said.
He said a manual count done 12 years ago was "laughable" and another done five years ago never surfaced in the public domain.
Mr Dunlop's count showed - when extrapolated over a full year - that Aratoi could expect 25,350 visitors, the equivalent of 70 a day.
A three-month count done in 2012 using an electronic counter indicated Aratoi would receive 76,400 visitors a year, or 212 a day.
Mr Goodwin said at a council workshop recently he had questioned whether a service contract council had signed for three-year funding would have been invalidated had Mr Dunlop's report and its findings been known at the time of signing.
It was his opinion council now had to sit down and renegotiate its service contract with Aratoi.
Councillor Pip Hannon asked what Mr Goodwin was wanting to achieve and said "you just can't take money away from a community facility". She said Mr Goodwin's "information has been received and duly noted".
Mrs Patterson said Aratoi had stated it was doing a lot of work on visitor numbers and accepted accuracy was "an important component".
Mrs Patterson said the debate could "happily go through to our next annual plan workshops".
