In a one hundred butterfly, you may desire to purely have a 4 sec or much less fade from each 50. seems such as you have been recovering your first 50, yet attempt to advance your persistence incredibly extra as properly, in view that 2d 50 is keeping some time back. there's no thank you to predict some time. you're able to have a purpose, and then shoot for that purpose, yet there's no genuine thank you to grant you a time over the internet. solid success at your meets.
