Welcome to the News community!
Rules:
1. Be civil
Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source. Clickbait titles may be removed.
Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.
7. No duplicate posts.
If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners or news aggregators.
All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link. Newswire services such as AP, Reuters, or AFP, are frequently republished and may be shared from other credible sources.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

you can't just screwdriver those things in there man you have to torque them in to the proper spec holy balls
I think they were checking how loose the others were rather than tightening them.
Well they are Phillips has so I can't imagine you can even torque them that much.
Interestingly enough they are not Phillips it is a very similar looking standard called Torq-set. The lines of the cross are off set a little which make it much easier to put a higher torque into them.

Is there any advantage to those over square (Robertson)? I still see 4 contact points when applying torque. So about on par with square and inferior to 6-lobed torx.
Well... It comes down to what material is used, as well as requirements and geometry for the screw.
I love Robertson, but with enough over-torque, you shear the head off the threads or worse, round the hole if there isn't enough rigid material around the square hole.
Failure modes are: stretching the material outwards until the bit slips. For the torq-set, you would need to shear the screw head material in front of each of the driver's tips off and out, much less likely than shearing the head off the threads, or shearing the bit itself.
Both have the great feature that screws placed on the head stay in place, making installation much easier.
Aerodynamically, the torq-set has a much smaller 'opening' than does Robertson or torx.
Engineering is all about solving a problem in a quality way now, and ideally, considering issues for the future. A downside could be ice/grit getting stuck inside the smaller opening, as an example.
