The problem interpreted on the board with Efapel's tactics are twofold.
Firstly, that the positive outcome does not necessarily mean that the decision was correct, it depends on other factors. A few more seconds due to not setting such a pace, or Figueiredo helping Antunes slightly more, and it's W52 who have to expend domestiques rather than Tavira when it comes to controlling the break going forward, rather than letting W52 keep their riders fresh. GCV is also tired faster if the gap gets bigger because Fred is working. So there were ways that the outcome could have been better. They have also won while doing similarly counter-intuitive things before, such as Antônio Barbio's win on Monte Assunção in 2016, when they pulled a successful 1-2 punch from the break... then took over on the front and chased their own break in which they had the sole escapee and the best climber in the chase group. Then, Barbio stayed clear so they got the stage, but they caught the chase group, and then their leaders got dropped on the climb. So they won the stage, but it was still a tactical fail. It looked for a good chunk of yesterday's stage like they were planning on repeating that, since Figueiredo is their best GC option and they were reducing his gains while seeming unlikely to make realistic gains elsewhere (unless we're genuinely feeling Moreira will be a GC candidate after 11 days, which we mostly weren't at day 1).
Secondly, the history of Efapel's tactical idiocy means that even when something works, they don't get the benefit of the doubt that it was by judgement rather than luck. They have a history of chasing their own moves, of passivity when they need to attack, of prioritising the wrong rider and sacrificing riders in better form, of supporting the chase when it is counterproductive or refusing to commit when they need to help the chase, and so on. Much like Jumbo-Visma or Movistar, who have a history of tactical fails that colour people's interpretation of their attempts to enliven proceedings and mean they aren't seen as sympathetically as they might otherwise be. I mean, take all those stacked lineups from the mid-2010s where they had by far the strongest team in the race, but blew it completely by sacrificing every option for the reanimated corpse of Rui Sousa, who inevitably failed hard in the final TT against the likes of Marque and César Veloso.
