Former Gloucester-Hartpury boss Lynn pointed out the absence of five key players – Alex Callender, Kate Williams, Gwen Crabb, Nel Metcalfe and Lisa Neumann – that impacted Wales’ strength and depth.
Those injuries contributed to performances dipping after a narrow opening loss to Scotland and spirited showings against France and England.
“The first three games we can be really proud of but we need to be better than the last two,” admitted captain Bethan Lewis.
“It’s completely within our control. It’s just making sure we work on it all when we are not in this environment, not just when we come in for seven or eight weeks. We have to be doing it consistently throughout the year.”
Wales might feel the gap is closing but there is still considerable work to be done to consistently battle Scotland, Ireland and Italy, let alone the French and English.
“It’s frustrating coming off after results like that when we know we have the ability to be better than that,” said Lewis.
“There is progress across the board, everybody is progressing so we need to learn quicker.”
Wales face Barbarians at Twickenham on Saturday, 27 June in a double-header along with Steve Tandy’s men.
That fixture is the day before the Premiership Women’s Rugby final, which will further hit Lynn’s resources.
