03-17 Compounding Experiment Summary

1, the written code language is the C language, the first two experimental code lines of about 50. The workload of one person is about 90 minutes.

2, the estimated completion of the 4th, 5 experiments required code line number is about 150, the time spent a person for 90 minutes.

3. The estimated number of lines required to complete the 6th experiment is 100 or so, and the time is 90 minutes for each person.

4, has now completed the first 5 experiments, the actual code line number of 110 rows or so. The total time spent is about 150 minutes. This obviously with the above statistics some gap, hope later according to own situation, make the correct estimate summary.
