Keep this in mind, you must do what you must do.
There are no “absolutes” when it comes to when you can work on certain sprint abilities with the proviso that the prerequisite abilities are in place.
Obviously maxV must precede speed endurance when maxV isn’t high enough yet. So you are free to address the maxV work as early as you want specifically because you aren’t currently fast enough for it to be “risky”.
We’ve already established that your 30m ability is more than sufficient to go sub 11 when maxV and speed endurance are in place; which they are not. Thus, it is in your interest to address maxV in the short term and not wait until some arbitrary point in the season.
If you’re ready you’re ready.
Begin your sessions with some block starts and short accels to get the volume you need to compliment the volume you won’t get with maxV and don’t be afraid to insert some speed endurance in low volumes one session a week.
The lower your level of speed the sooner you can address abilities that a very fast runner will have to wait for due to their output levels.
More speed is almost always the key; the difference lies in what each individual must do in order to develop it.
