Also big numbers are grouped by 4s with natural language (as is done in Chinese), but the commas are in groups of 3 (at least that’s what I’ve seen).

I’m not sure I understand your post.
What is “natural language”?
Can you give an example of “natural language” that groups the numbers by 4?

I presume the difference between the number being written as if it is pronounced, or as an abstract entity. The pronunciation is in groups of 4, but when writing down the string of numbers it is often written in groups of 3.
My family here in Japan confirms that they write it in the following ways:
127, 437, 735
1億2743万7735
The first is as a number, for example as seen in accounting, or statistics, or scientifically etc. The second one you can on price tags, or in some newspapers, or old-fashioned writing.
In fact, it’s often combined as well: 15.6 million can be written as 1,560万 (such as while subtitling a TV show)

@Vsotvep hit the nail on the head. Perhaps a better word would be “spoken language”?
This was my example. Expanded, it’s “천이백삼십사억오천육백칠십발만구천십이” which is something like:
one thousand two hundred thirty-four Hundred Million
five thousand six hundred seventy-eight Ten Thousand
nine thousand twelve
As you can see, big number names come in powers of ten-thousand or groups of four decimal digits (만 = 104, 억 = 108, 조 = 1012). These come directly from Chinese (万, 亿, 兆).
PS. Any Chinese speaker able to say what is more common? 万亿 (from @jlt’s Google Translate screenshot) or 兆?

Actually the next number in the sequence would be 4096. No one should attempt that!

Hmm… correspondence looks for around 1 move per day, and and there are 16 hours in a day. Blitz players can easily hit 720 moves per hour (5s per move).
So I’m thinking the limit is somewhere in the ballpark of 10k? @_Sofiam you’re going to have to up your numbers! 
(Of course there is still the question of whether someone can do nothing but Go Simuls for 200 days straight…)

This seems slow 
I think I average less than 3s per move, less than 2 if I try to be quick.
With slow settings you don’t have to play one move in every game every day. And the new cycling order helps a lot (I didn’t have it wheh I was at 1500!)
I think 10k is humanly doable.
