"We have also noted some singles players have said they had no problem serving," he added.
The experimental rule mandates that "the whole of the shuttle shall be below 1.15 metres from the surface of the court at the instant of being hit by the server's racket".
A couple of high-profile players, including 2012 Olympic champion Lin Dan of China and Denmark's world champion Viktor Axelsen, have publicly expressed opposition and Viktor Axelsen, 1.94 metres in height, posted a video on social media, in which he mocked the rule by serving on his knees.
"Obviously, any time change is proposed, especially to such an essential aspect of a sport, there will be a wide range of views. We will take all of these into account." Lund responded to the complaints.
"There have long been complaints regarding the service laws in badminton and BWF wants to ensure greater fairness in service judging and that's how the laws are applied," he said.
He also stressed that before the experiments, there had been detailed consultation with "top coaches from a number of badminton's powerhouse countries".
Following the Badminton Association of Malaysia's proposal last year to try fixed-height serving, to which BWF member associations agreed, BWF started the testing at the German Open on March 6, followed by last week's All England Open.
Testing is expected to run until the end of the year.
According to Lund, BWF will determine "if 1.15 metres is the correct height or if it should be slightly higher" depending on further feedback.
