In year 2000 I gave marks on the edge and center of the mirror only.ycw 寫:題外話。
為何2000及2002的同學錄大部份皆沒有平均分?

Later I realise that an average mark will give an overall picture on the mirror--- I am talking about the degree of polishing not the figure i.e. spherical surface? parabolial...etc.
For edge ---may be we are talking about 0.4cm or 2~4cm,
For center---may be just a hole or about 80% to 95% of the whole mirror surface.
Average rating is more appropiate.
Where some mirror got the average mark and others did not was my fault --- I forgot.
