Three numbers to define Vera Pauw's month: 75, 31 and 23.
Over seventy-five phone calls to inform players that they were either in or out of her World Cup training camp ahead of the 22 June friendly against Zambia.
Thirty-one players who recieved the good news that their World Cup dreams remain intact.
And twenty-three, the lucky group that will - on 29 June - be given the golden ticket to Australia for the tournament itself.
All of this has been further complicated by a European Clubs' Association [ECA] directive that players can only be released for international duty from 23 June.
FIFA discussions with the ECA continued on Friday as several countries pushed for a 19 June release date. It meant that Pauw couldn't 100% confirm when Katie McCabe would be available. Her club season only finished two weeks ago, but developments in England on Friday evening offered more clarity as the FA received clearance from the Women's Super League to bring players into camp on 19 June.
That should allow Arsenal star McCabe to link up earlier and potentially feature against the Zambians, which is welcome good news for Pauw, who's currently enduring the agonising process of whittling down her squad.
"You have to make choices. I wish I could bring them all. We can't."
"Halfway I had to stop for a moment, to be honest," she said on Friday when asked about informing players they have not made the training camp.
"The players I called were disappointed of course, most of them had expected the call. It's devastating. I’m very much aware I have broken dreams and it will have an impact on careers also.
"We’ve not taken this lightly as I said all the time. It’s elite sport. You have to make choices. I wish I could bring them all. We can’t. So believe it or not, with all the clubs and everybody on Monday, I had to make more than 75 phone calls.
"But the shift was done and I’ve called every single player again this week to see how they are doing. And we have offered them support because it can have an impact on their moves and the way forward."
There is another number for Pauw to wrestle with: 27.
Although 31 players have been named in the wider squad, only 27 are definitely available to face Zambia at Tallaght Stadium, with McCabe in limbo and US-based trio of O'Sullivan, Sinead Farrelly and Marissa Sheva not arriving until 26 June due to the NWSL season being in full flow.
It gives some players one last big chance to make the plane, particularly the likes of Leanne Kiernan, back in the squad for the first time since last September after an ankle injury effectively wiped out her season. Peamount United's Erin McLaughlin is another who will look to stake a claim, with Pauw adding: "Every player that comes into the camp has the same chances.
"We have to make our final decisions on the basis of what they show in camp. That is for everybody. Of course we all know there's a few that are pretty sure about their place, but for [Erin] or any other player that’s on the fringe of the squad, it’s completely open.
"There’s players who have played their last game at the end of April. That meant it would be up to 11 weeks of no football in between the last league game and the World Cup. Everybody would understand that that is not possible."
Ireland will gather together on Monday, with training sessions split between UCD - where they'll make use of the student digs - and the FAI National Training Centre at Abbottstown over a four-week period. Players will get the weekends off to have a break and decrease the risk of the camp becoming stale.
It is, after all, a long run-up to what is going to be an incredibly intense trip Down Under.
"Every player will have their own room in an apartment, their own bathroom facilities in a central place so they can live more or less a normal life," said Pauw.
"Our training sessions will be there and it's more like a club session. They will come on the pitch and then have a lot of freedom. We didn’t want to set up training camps for the entire six weeks because you get tired of each other so this will keep them fresh.
"The breaks are important to recover from the load that we give them. Every single session, they have to be fresh and ready because otherwise indeed, [the ECA] would be right that the load on the players is too much. But the way we do it is in that slow build-up with lots of moments that they completely recover, it will bring them fresh and at a higher level."
Megan Campbell, Niamh Fahey, Lily Agg and Kiernan are among those who need to be handled carefully due to the lack of minutes they've got under the belt in recent weeks, but the main injury worry right now is Aoife Mannion.
The Manchester United centre-half was so assured in her two caps [against China and the USA] that she'd looked nailed-on to start against Australia in the World Cup opener on 20 July. However a knee injury sustained in club training two weeks ago is now a real cause for concern.
Mannion is not in the latest squad, with Pauw revealing: "That depends on Monday when the knee specialist has seen her. She's coming out of her brace. It’s really tight.
"She will see a knee specialist on Monday, then we will know more. The way that it's being brought to us, it will be tight but possible. I hope… fingers crossed."
It's on to a crucial camp then, as Pauw's charges tread the line between proving their worth in training and avoiding any uneccesary, dream-shattering injuries.
And after all that, the really hard part comes for the manager: naming her final World Cup squad.
"The tightest decisions will come still," she admitted. "The players that are closest, of course also players will drop out when the four other players come in. Those are the ones that are tightest."
