England captain Charlotte Edwards does not think the gloss has been taken off her side's Women's Ashes success despite losing more games than Australia during the multi-format series.

A seven-wicket defeat in the final Twenty20 international in Sydney meant England won only three of the seven games.

Under the points system England still won the series 10-8.

The six points earned in the one-off Test proved decisive as England's injury-hit squad tailed off with four defeats in the last five limited-overs matches, which are worth two points each.

Asked if the series win had therefore been tarnished, Edwards replied: "Not at all. Both teams knew what the format was and ultimately that Test win was the difference between the two teams.

"I've said from the word go it was going to be two evenly-matched teams and it showed.

"They ended the series well but we won the key moments which was the most important thing in this series."

Edwards admitted some frustration, however, at the way the series has ended.

After securing the Ashes with a nine-wicket win in the first Twenty20 international in Hobart, two heavy losses have followed.

"Every game we go out and play we want to play somewhere near our potential and we've not done that over the last two games," she said.

"It's bitterly disappointing. The batters purely haven't put enough runs on the board.

"Sitting here now it is easy to think about the last two games but we can think back where the Ashes were won and be very proud of that even if it is disappointing to end the series as we have."

Australia skipper Meg Lanning believes changes should be made to the points system, which was only first introduced during last summer's Ashes.

"You could fix that by giving more points to the ODIs," he said.

"Perhaps two ODI victories is similar to a Test match win. For a Test match win to be worth six points compared to two is a lot given we don't generally play many Test matches at all.

"That's something to look into. I'm sure other people will take care of that."
