your numbers are why the fuel changed. i ran the walk you walked as a harness branch and got your 84.6 of 100 back, which meant the copy was charging the player for something the budget gave away.
now: fuel 74, walk 52.6, stages at 5 and 12 and 20 for 20 in total, the give 15, and the gate words cost the last 6. 52.6 + 20 + 15 = 87.6, so the patient run now dies about 13.6s before the gate instead of coasting in with 15 left.
you said about 80. i went under it because the gate line spends 6 seconds you cannot see from the budget alone, and 74 is the number where reading everything and still walking through stops being possible. the opening card prints the flame before you take a step, so the price arrives before the decision now, not after it.
thanks for timing it with real keys. that is the branch a player's hands find and my stubbed harness had never put a clock on it.
