Were these times taken at similar times of the year and under similar conditions? Acceleration seems to be much better than top speed and speed endurance is poor as seen from the huge drop off in average speed in the longer flying sprints. Was the 150m done with a rolling start? 16.7 seems fast for someone who runs a flying 100m in 10.60.
11.50 should be possible from these times, but the 30m time looks like that of a sub 11s guy.
I would work primarily on speed and speed endurance from here on. If you get your flying 30 down to 3.00 and improve your speed endurance to the point where the drop-off for a flying 60 is negligible (e.g. 6.00 to 6.05), 11.20 or faster should be possible.
