HP 30b
Count: 72,517
Code: LBL 00 + GOTO 00
(as first program in memory)

And that's more or less ok, between 130x and 280x, ~= your 34s.

Bear in mind, those were 60-second tests, with a shorter program and pre-loaded stack (label searches may be faster).

The 58/59 used weird labeling. You had A-E corresponding to the five hot-keys at the top, and A'-E', the same hot-keys prefixed with 2nd. These would normally be used for your program's entry points. You could also use (almost) any other non-numeric key for a label, which could be called with SBR or GTO. GTO with numeric arguments would be interpreted as a branch to a step number, so that's probably why you couldn't use 0-9 as labels.

Program steps were 100% not merged, so this scheme was probably easier for the parser/state machine. Treat any key code after LBL/GTO/SBR as a label, and a single digit key-code (00-09) after GTO/SBR as a trigger to grab the next step's key code and build a 3-digit step number out of them.
