Indeed the terms preceding the first term >2 are always 0 or 2 since
all lucky numbers are odd
(while the primes start with the even 2 which leads to the initial "1"
of each row).

The equivalent of
oeis.org/A036277 		Position of first term > 2 in n-th row of Gilbreath
array shown in A036262.

for lucky numbers would be :
(next term > 100 000).

The growth behaviour seems at least as fast as that of A036277.
