Percentage error introduced by limited accuracy of measurement of l is only $0.1\%$ while due to measurement of time is $0.94\%$ .
As $\delta t$ is fixed equal to least count of stop watch , to improve the situation , t must be increased .
In another words time for more number of oscillation must be recorded.
