Did you not read the part of the sentence after you bolded it? I said, you will reach a higher top speed?
I don’t think everybody hits “max acceleration” between 15 and 20m… Your greatest change in acceleration would actually be 0-10m and the rate of acceleration would start dropping after the initial steps unless you are actively holding back. Your top speed would depend on how fast you are, but if you are 11.0 or faster it’s probably 30m or later.
How slow are you? You may not have the strength or fitness levels to really train any of those qualities “very well.” If you are that slow, hell, 30m IS top speed because you are probably hitting top speed at 20m or so.
