Well, first look at the meters you got. 42 in the context of admiring Temple Building makes no sense to me, as 42 is a positive meter, Jacob leaving Haran with two families, 21 years after he entered to get but one wife. But then Eph1 talks of two walls, so if admiring one temple led to two...
Then your 126 meter in connection with naming four of the apostles, could be a kind of memorial. At least two of them are dead when Mark writes: Peter's meter (and Jude's too, he being brother of dead James and BOTH of their names being Jacobus in Greek).. is 126, 28x2=56+70 in 2nd Peter, https://vimeo.com/channels/bibledatelinemeters/122425890
So there is some possibility those meters are the right ones?
Okay, to your question: thinking over 'your' 196 versus 'my' 231 as the overage ending in Mark.
196=7+14+21+28+35+42+49. All the meters come from these, and all of them are used as dateline meters in the Bible I've seen so far. So 7+49=56, so the total doesn't need to go that far. As you do the actual addition, you'll see the others at each +.
231, is Dan9:24-27 meter, http://www.brainout.net/Dan924HebParsed.pdf
. I did a video on it where I got interrupted by God in the middle for making mistakes and didn't edit that out (too long, sorry)

So it's as if, at 231, Mark ends with a meter mnemonic as an epilogue, reminding the reader of God's response to granting Daniel's prayer for more time and Temple Rebuilding. Idea that the close of the 1050 'play' is that God will grant Church more time maybe based ON Daniel's prayer, since after all Christ dies at the start of the 62nd week not the end.
The sum is also equal to the initial NT dateline meters, 7+14+21+28+35+42+49+56+35 . What's interesting here is the doubling of 35 and that JOHN'S GOSPEL alone has a 7 initial dateline meter.. not written yet. So if the prophecy of dateline meters comes true then again you know Mark's Gospel Chap 13, comes from God.
I wonder how many of the meters use this same style, if indeed this is the style. For Matt24's 63 ends up being a prophecy of Luke's meter but also other NT books (not all of them, unless you break the 63 into 7s). Luke ends with 35, which ties back to his initial chapter meter, and of course Matt24 does too.
Bigger point is for sure, that these numbers are deliberate. Whether we can say the above meanings are the right interp of them, is a whole diff kettle of fish.
