3100 maybe, because 2100 is not possible.

2400 is the minimum even if you get the luck of the devil and get every single time 2 frags.

You have a misunderstanding... a 1 edo hashi per 40 pulls is a figure to show you that you are getting 1 or 2 frags per 60 pulls which means an average of 1.5 frags each 60 pulls which is equal to 1 each 40 pulls... so edo hashi will be recruited at 3k scrolls in normal cases .. but here is the scenarios if you pull during rebates

800 pulls rebate:-

you need only 734 seal scrolls getting 66 free scrolls from rebate

So 734 which is by rebate =800 so each 734 pulls will give you 800/40=20 frags+5 frags rebate

Assume 5 frags will be pulled in free pulls so you need 75 frags

then 75 need 3 rebates of 800 pulls which is actually 734 then you will need 734*3=2202 pulls

300 pulls rebate:-

you need only 264 seal scrolls getting 36 free scrolls from rebate and then after the 300 pull you will get extra 30.

So 264 which is by rebate =330 so each 264 pulls will give you 330/40=8.25 frags

and since we assumed that you will get 5 frags in free pulls so you need 75 frags so 75/8.25= you will need 9.1 rebate of 264 scrolls which is = 2400 pulls also.

So 2400 pulls+200 free pulls= 2600 pulls will give edo hashi in rebates of 300 and 2202+200 free pulls =2402 in rebates of 800.

Last advice, if you got both your super rares in GNW treasures before reaching edo hashirama then ou should go for edo jins treasures to get new ninjas and edo hashi fragments.

2341 is the minimum and is official that is the minimum.

my guess is or that you didn't take in account the free rolls (over 200 since the treasure was added in the game and they matter) or you just made a mistake in calculating the number of rolls you did if you really never got any fragments from p2w events (happens, is hard to take track of the rolls, many people simply rely on the number of rares they got to do the calculation, but is a wrong way to calculate it).

that said, as far as i know, the officially claimed chance in CN to get him (they have the ratios on show for the public audience, differently from us) is 1:3030, so means that 3030 is the average number of rolls to get him (since our treasure works exactly like their one) and this actually matches almost perfectly my current outcome (i have 43 frags of him with 1600 rolls in total done).

300 7 times means 7 months of free draws. Them alone are 100 rolls. You said you got him last month, so 13/14 months after gnw treasure was added in game. 13 months of free draws = 200 free draws. 2110+200 = 2310, lets add in a mistake of 30/40 rolls in the calculation and you got the number.

That said, as garv said, 2341 is the minimum (the first rolls in the 40th range of 60s), so you just made a mistake in calculating this.
