To 100M to 75 Bits[CODE]YYYY-MM 71-Exp 71-Days 72-Exp 72-Days 73-Exp 73-Days 74-Exp 74-Days Total-Days
2016-11 287,983 1,514,036 353,420 3,721,261 376,132 7,957,670 400,961 17,290,758 30,483,724[/CODE] Assumed: - All exponents 66M to 99M should/will be factored to 75 Bits. - Equal distribution of exponents in each Million range. - Used GhzDays for x.5M exponent for the entire Million range - Reduced by exponents expected to be factored in each range DID NOT account for what P-1 would eliminate though I believe that is NOT done until after TF to 75 is done. |

1. All exponents up to 80M have already been TFed to at least 75 bits. 2. For some users going to 76 bits makes sense above 80M, depending on their cards. 3. There is no rush on this. The LL'ing is far behind. |

There are a almost 23,000 between 66M and 70M not yet at 75 Bits. I suspect these exponents have already been LL'd. So this would be more of a DC-TF ... granted DC is a VERYYYYYYY long way from there. |

LOL... Yeah, DCTF to that range and depth is a very long way away (read: years). LLTF to 76 bits is clearly more important at the moment, and interestingly some are already working that for the P-1'ers currently. |

Totally +1 ! |

5 and a half months later (April 16, 2017)[CODE]YYYY-MM 71-Exp 71-Days 72-Exp 72-Days 73-Exp 73-Days 74-Exp 74-Days Total-Days Percent
2016-11 287,983 1,514,036 353,420 3,721,261 376,132 7,957,670 400,961 17,290,758 30,483,724 100.00% 2017-04 185,543 954,413 259,261 2,659,396 304,180 6,306,903 341,956 14,554,544 24,475,256 80.29% [/CODE] Almost 20 Percent progress. Understood that from 83M on we are going to 76 bits ... and maybe before 100M to 77 bits? |
