Drop below 30 seconds in 50m freestyle swimming

So this probably won’t be achieved any time soon.

The Northern Israeli Championship took place Saturday. I reckon I could’ve achieve that goal there, but as it turned out, there were no springboard (not sure if that’s the right word), which halves about two second of my score.
so my score was 30.96, which is pretty close to my personal record of 30.84.

... is my primary style. I usually do sprints of 50m (which is two standard half-olympic laps). My best result last year was 30.84. Since we have 8 hours of swimming per week this year (instead of 3 hours/week), I was hoping to finally drop beneath 30 seconds.
As a matter of face, I’ve already done this last week during session, but my coach didn’t stop the clock. Although he assured he’s seen the clock say ‘29.09’, I want to be sure before I finally achieve this two-years-old goal.
(For comparison – The Israeli record for my age (17) for he abovementioned is 23.82.)
