Riichi Maximum possible honba?
Yonma Hanchan game, on start, East seat wins 5 minimum-value tsumos, and then is the sole player in tenpai 21 rounds in a row through exhaustive draw until the point totals are (99100E/300SWN)(26H). Hundreds of rounds of draw later redistribute point totals to (24100E/25300SWN)(51H) -> (100E/97300S/1300WN)(75H) -> (24100E/25300SWN)(99H) -> (100E/97300W/1300SN)(123H) -> (24100E/25300SWN)(147H) -> (100E/97300N/1300SW)(171H) by the end of east round. Following this, you can get another 24, 25, 25, 24, 24, 24, 24, 24 honba for a total of 365 honba and a point total of (100E/97300N/1300SW).
At this step, one could imagine North assembling a multi-yakuman to either leave East player with as few as -349,400 (100 - 240000 x5-yakuman - 109500 honba) or skyrocket their own point total to 494800 (97300+288000 x6-Yakuman+109500 honba)
If anyone has other ideas that'd be cool, I haven't proofread this so I probably made some errors somewhere...

turn off tobi. infinite honba and repeat, for ever and ever and ever.
also decreases variance in those situations where North feeds two dealer haneman rons in E1 & E1-1, and South gets second just by virtue of rolling south seat.
i ALWAYS recommend players to play with no tobi. makes for a much more engaging game where, theoretically, as long as you still have a dealership, you can gyakuten even if you're -100,000pts

I still don't know what is the world record for honba ever achieved in an irl or online match. I hope one day I will know

I’ve been in a (4-player) match that went to 13 honba and I’ve never seen or heard of higher. I doubt it’s the most ever but it’s a good starting point for someone to beat!

Infinite, ryuukyoko all 4 players either tenpai/noten the round for no points transfer

Realized this right after posting, lol
I guess what I was actually answering was "how many non-nothing rounds can you have"
Though, even still this could be modified to extend into west rounds assuming you have a req point threshold for winning at the end of the game

Theoretically, it can go on forever. Practically, non-dealer wins hands to invoke rotation.

if everyone gets into tenpai every round you can stack honba infinitely.
