How Should The Ballots Be Shaded?
Ovals should be shaded fully. Marks are evaluated based on a COMELEC defined sensitivity-level. For example, a half-shade (filling half of an oval) will be evaluated by the Automated Counting Machine whereas a dot would not. This protects against accidental marking of an oval. Furthermore, the practice of shading an oval completely shows that the voter is actively and with full intention selecting the candidate of their choice.
