Good afternoon.

As a source for the changeset you mention "local knowledge", but you also comment "from other sources". Which other sources are you referring to?

This was pointed out to you before but the changeset comment should contain a short description of your edits, for example "improve road classifications", for more details see here: https://wiki.openstreetmap.org/wiki/Good_changeset_comments

Regarding the classification changes that you made recently (especially upgrades from tertiary/secondary to primary), several experienced local mappers think that the current function and importance of these mostly provincial roads does not meet the criteria for primary classification (roads connecting major population centers, see: https://wiki.openstreetmap.org/wiki/Philippines/Mapping_conventions/Roads/Classification).

For example afaik Matanao-Columbio still has a major ford near Sinapulan and is therefore for most cars not yet viable as a connection from Digos to Marbel/Tacurong. Although primary classification will probably be appropriate once bridge is built and concreting of remaining unpaved sections is finished.

Another specific example that I mentioned to you before is the road from San Jose to Laak. This road is still unpaved and essentially all long distance traffic is using the nearby already finished Palavilla-Lasak Road. The more important road should have the higher classification even if it is not always the shortest route. 

Please don't repeatedly change classification of the same roads if you're not willing to respond to questions and discussions.
