I made a quick analysis of current swimming world records of female and male swimmers and here are my findings: (50 LCM pool, 50,100,200 all styles including 200 IM, 400 free and IM, 800, 1500 free)
Female swimmers are 10.96 % slower on average
In 50, 100 and 200 events the differences are 11.9%, 11.5%, 11.3% respectively (more distance, less variance)
Largest gap is in 50 back (13.6%)
Smallest gap in 1500 free (7.8%)
Considering the average of 50, 100 and 200 of 4 events, largest gap is in backstroke (12.2%), butterfly (11.7%), free (11.4%) and *** (10.3%).In athletics, 100, 200, 400, 800, 1500 and 3000 track events, the gap is 10.43%. When I took out the incredible 100 of Florence G. Joyner, the gap is nearly the same as in the swimming (10.98%).
Lowest gap is in 100, with 7.7%, largest gap is in 800 with 12.0%, but most of the differences are between 10% and 12%.
What do you think?

Here is another analysis:
If we index the world record times of freestyle events as 100, here are the results: (LCM)
For female swimmers:
-------------------50m. 100m. 200m.
freestyle(index)--- 100---100---100
butterfly---------- 106---106---109
backstroke-------- 117---112---110
breaststroke------ 126----122---122
for male swimmers:
-------------------50m. 100m. 200m.
free(index)-------- 100-- 100-- 100
butterf.----------- 106-- 105-- 108
back-------------- 115-- 111-- 110
***.------------ 126-- 124-- 124
Here are my conclusions:
butterfly is very fast in 50 and 100, but lose pace with distance (as expected)
backstroke is slow in 50, but the gap decreases wth the distance (I think mainly the start of backstroke is a handicap an its effect is more in shorter distance)
breaststroke has a relatively constant correlation with freestyle and it is approx. 25% slower than free.
