Mulitple entries in the AF 4098 Take-off worksheet-about 50, I'd guess. A good engineer could do one in 20 minutes, if there wasn't a difficult climb gradient problem. We always had Vmca2, refusal speed on the pilot's card. Normally, refusal and rotate were computed and then compared to Vmbe and Vcefs (critical engine failure) and the limiting one became Vgo (V1). On take-off the PM just called "GO" signally stopping was no longer an option. Did a near GO stop at Sigonella once, just made it. Then "rotate", of course. Gust increment was added to Rotate and V2. It was a very marginally powered aircraft, or too heavy, if you prefer. Above 712,000, its originally gross weight, additions were notable in performance. OEI climb gradient could be as low as 2.3% with no obstacles. Surprising amount of this stuff stuck, but I instructed to pilots. Who were not impressed!
KIAS, not EAS, but Old Smokey smiles at you mentioning it.
