Strikes per sec, S=5.8t on average.
If t=30, S=174 which is about 3.5% above actual. This puts it into ±10% range.
If t=22, S=127.6. If we add the totals for 4-7 seconds we get 133 seconds. Therefore we have an actual estimate of 133 strikes in 22 seconds=6.06 strikes per sec, which is 19.3% above average, putting it into the ±20% range.
