The lip-touching streak breaks for just one number: walo (8) and another streak starts with siyam (9) all the way to siyamnapu’t-siyam (99) by how two-digit numbers are pronounced. For example: labing-isa (11), walompu’t-walo (88).
(I think) there’s a lip-touching streak that is longer than this: walong daan at siyamnapu (890) to siyam na raan siyamnapu’t siyam na bilyon, siyam na raan siyamnapu’t siyam na milyon, siyam na raan siyamnapu’t siyam na libo, siyam na raan siyamnapu’t siyam (999 999 999 999).
Nah, definitely happens at 300 with 三百
Edit: in japanese, but I didn’t list my language since OP didn’t bother.
八
Empat
apat (4), lima (5), anim (6), pito (7)…

In Chinese yes, in japanese, no (8 would be hachi, 300 is sanbyaku but that n before b is pronounced as m)
