(For those who don't know, this is obtained by baking one million cookies in the first 15 minutes of a Born Again run.)
Has anyone here managed to get this without cheating? After my most recent ascension I decided to have one more serious crack at it, and I have concluded that it's impossible to get without either cheating or being very lucky in getting click frenzies and other bountiful outcomes from golden cookies.
What I did was this: I did one Born Again run, using the most efficient buying strategy as given by my spreadsheet. Each time I bought something I recorded the purchase, to keep track of the sequence. Continually accessing the spreadsheet and writing down purchases of course took time, but on this run I was not concerned with finishing the run quickly, only with finding the most efficient buying sequence. I kept going until I reached 2 million cookies, which took about 48 minutes.
I then ascended again, and bought items in the sequence I had written down. Throughout the run I would click the big cookie until I had enough cookies for the next best buy, buy it, and then go back to the big cookie. At the beginning most of the time was spent manually clicking - later on the number of cookies produced at each click became negligible compared with the CpS so I gave my finger a bit of a rest.
The best I could do was one million in just under 19 minutes. I am convinced that I could not improve on this unless I got very lucky with golden cookies, or did it during Christmas season. I think I'll give up on this particular achievement.
