Overall. Considered, but have not seen much of the logic. To demonstrate the rationality should be such as to improve the system. It damages the result of improved results, however.
Overall, considered good, but not as much logic. Why not demonstrate results that should such a system be adjusted?, แกิด results from the adjustment to take effect?
On the whole, be deemed to be good, but it is not seen as much logic to NOT show up as a result of a cause as it should be such as to improve system performance, and how the LORD caused by the update, and then effect?
