Shiro is at 177 points
Shiro is not a given. While he currently has the points there are still a lot of events left for him to get knocked off the participant list.

There's only Red Fight District for Europe and the CPTA Cheng Du event in Asia for ranking events. In the U.S. there is only Defend the North for ranking events, the wild card tournament of Costa Rica CPT ranking event. There's just little to no events for the 2nd and 3rd tier players that might catch Shiro for them to attempt to jump over. Luffy will continue to gatekeep Europe's ranking events so he can get a good seed. U.S. top players like Snakeyes, Dieminion, Strider 801 and Nuckledu will continue to place well, and Infiltration might show up to gatekeep in order to practice for Canada Cup the next week. Only Smug since he's local would be a threat to try to get points, but he plays a character that either blows people up or gets blown up and trying to win a tournament with that sort of character is hard over a whole tournament.
For Premier events, there is still SCR (US), BGS (Brazil), Milan (Italy), Canada Cup (Canada), Ultra Hakkyushu Cup (Japan), Dreamhack Winter (Germany), and Capcom Cup Asia Finals (Singapore). All the best international players that already won or have high points will travel to the events (outside of Luffy) due to the high prize pots that each event has. The only exception is for the Brazil Game show but that is fine, that is expected, and CPTA finals which is an invitationals for the winners of each CPTA qualifier.
If top 4 of a given premier event are already qualified, then the premier spot becomes an open field spot which helps out Shiro. CPTA Finals are already filled with gatekeepers (Infiltration, Bonchan, Nemo, Tonpy, Misse, Xian, Xhao Hai, MOV), and the best players who doesn't have a guaranteed spot is Bonchan and Nemo, both players who have more than enough CPT points and will free up an open field spot. Tonpy, Misse and Xhao Hai are also players with a lot of CPT points that if they get that CPTA finals spot, will help a player like Shiro.
Basically, Shiro (and Strider 801, and the people directly under them) will be fine for Capcom Cup. For Shiro to not make it, just about every Premier spot has to be taken by a player who is not high on the CPT list currently. That's 7 spots up for grabs, it's just about impossible for 7 Street Fighters players who don't have the points to grab each every Premier spot. There's just not enough talent of the 2nd and 3rd tier level for that to happen. Also, those players will have to travel to just about every ranking event left (like Gonzales is trying to do, and Shiro has done in Asia) and need to win one of them.
It's just not going to happen.
