Ospreys head coach Steve Tandy described fly-half Dan Biggar's 1,003-point Pro12 tally as "incredible".
Wales' Biggar, 23, scored 18 points in their to become only the second player in the tournament to reach four figures.
Connacht's Dan Parks tops the tournament's tally with 1,507 points.
"It's incredible that someone so young has achieved what he has in this competition," Tandy told the region's website.
"But [it's] no less than he deserves.
"He is the complete professional in everything he does, he is hard working, diligent and an example for others to follow."
Biggar made his Wales debut in 2008, but did not play in the Six Nations until the 2013 campaign in which they successfully defended their title.
However, Biggar was the only member of the Wales starting line-up that beat England 30-3 on the final day of the 2013 Six Nations not to be selected by Warren Gatland for the British and Irish Lions tour to Australia that followed.
Instead, Ireland's Jonny Sexton and Owen Farrell of England shared the Lions fly-half duties, along with Scottish utility back Stuart Hogg.
However, Tandy underlined his faith in Biggar, whose Pro12 match average is 10.67 points from 94 appearances, compared to Parks' 9.85 points from 153 games.
"He has always been fantastic for the region, he is proud to play for his local team and I'm absolutely thrilled that people are starting to acknowledge what he is about," said Tandy after Biggar scored a try and kicked five conversions and a penalty against the Irish province.
Although Tandy said he was happy with their attacking efforts, he wants improvements in defence and discipline.
He praised the "big achievement" of scoring six tries at Galway's Sportsground.
Tandy added: "We've had a very tough start to the season, with three of our first four games away from home, so to be talking now after four games and we're still unbeaten, that's a great effort from everyone who has worn the shirt this month. They all deserve a pat on the back for that.
"Our attacking game over the last couple of weeks has been very good, we're heading in the right direction in that aspect of the game and it's pleasing as a coach to see the team making strides in that area.
"Other areas of our game are letting us down, though. There is lots of work to be done on our discipline and our defence. It's not quite clicking."
