As far as I am aware it has always been 10K per day online. 
ahh i mean because reach was 1k per day. I remember some one saying 2k for halo 4. So i was asking from reach to halo 4 is it 10k per day now 
So its deffo 10k you can bring online now?
I cannot say for certain as this is my first day adding XP so I will have to wait 3 hours to test 10K. Although nobody has reported 10K not working. I will add all daily XP adds to the personal log so keep updated on the main post. 
Iām talking about the limit. Your supposed to be only able to take a certain amount of xp online. Say you add 1 billion xp but when you go online only 10k xp carrys over. Itās this limit im talking about. So you say youve add 10k and it works? it carrys online?
edit
nvm just read it again, youve not tested it yet lol
Hereās what you do for the first time 250,000 BOOST with SPARTAN POINTS
Just add over 250,000 offline like 250,001 and then go online and it will say you can only take 250,000 do you want to forfeit so many credits then you click yes.
It will correct the spartan points and achievements for you instantly
I tried 10k but it didnāt go on. Maybe I did it wrong. I transfered my GT, opened up editor added 10k, saved went back on and nothing
250K XP first time limit and 10K XP daily limit any time.

I did 250000 and still goin strong here im level 34 now added 10000 yesterday got to 32 and then got to 34 legit still got exp and sp points no reset no ban and i have yet to reach my daily credit limit lol
There was originally an XP limit of around 9,000 from matchmaking games although according to some posts on the waypoint forums this seems to have been lifted. I have yet to see anybody hit a cap since. This leads me to believe this may be the first time a cap does not exist.
Although itās possible theyāre gathering information before deciding a suitable cap.
I can confirm a 150,000 xp cap per day. My buddy has hit it twice already. I keep telling him he has no life.lol
Actual game play, not xp editor. To prevent confusion.
Ask him to release some tips! 150,000 a day is unbelievable!
Like i said he has no life on his days off. just a lot of game playing. I figured an average of 2000 xp per game, hes playing well over 75 games a day. Thats what ive played in three days
My girlfriend stops that from happening for meā¦ that and sleep ^^.
A lot of people seem to be hitting this cap after looking around the forum. Could some of you release some tips for us to use along side the XP editor? 
I modded the 250k when I started and now I am a rank 39 two days later.
Iāve been hitting the XP Limit for the last two days. Now what I donāt understand is how long the limit lasts. In Reach when I hit it, at 6 A.M. the next day it would be lifted. In Halo 4 when I hit it and when the clock rolls around 6 A.M. it doesnāt lift. Does this mean that it is 24 hours exactly from when you hit the cap or what?
The cap resets at midnight EST. I will add this to the main post.
I as well did 250,000 and that is a xp limit for 1 day, since its the limit you donāt get anymore xp nor SP, but I do 10,000 daily and am level 35 with 1SP adding with each level up, still have not been reset or banned.
im sure they will ban people for using this? and they might account ban? 
You should gain 30SP after your first match. I did and quite a lot of other people did.
I imagine they will do it in action based on previous offences such as resetting XP and giving us an XP ban (cannot gain XP for a certain amount of time) slowly increasing from 24h to permanently. Although we will find out when action is taken against my account and the thread gets updated.
