Dear seqfans,

Distribution of frequences of 
"Dropping time" (DT) values  
is remarkably similar in each 10000 n's:

f1...f4 = frequences of DT in 1st...4th 10000 n's

{DT,f1,f2,f3,f4}
{{0,1,0,0,0},
{1,5000,5000,5000,5000},
{3,2499,2500,2500,2500},
{6,625,625,625,625},
{8,625,625,625,625},
{11,236,234,234,235},
{13,273,273,274,273},
{16,116,117,116,119},
{19,73,74,72,75},
{21,104,101,105,104},
{24,55,51,53,55},
{26,71,73,73,73},
{29,37,41,37,31},
{32,38,33,23,26},
{34,33,36,34,46},
{37,18,17,24,22},
{39,33,26,33,33},
{42,16,20,16,13},
{44,23,22,28,17},
{47,7,15,13,9},
{50,8,8,8,13},
{52,12,13,8,16},
{55,5,9,10,6},
{57,10,13,9,14},
{60,10,2,6,9},
{63,5,5,6,5},
{65,9,7,8,5},
{68,5,4,5,3},
{70,10,10,7,2},
{73,1,4,5,4},
{75,5,5,1,6},
{78,4,3,6,2},
{81,5,1,1,3},
{83,2,5,4,2},
{86,1,2,3,0},
{88,7,2,4,1},
{91,1,2,1,0},
{94,2,2,1,3},
{96,1,1,4,4},
{99,1,2,0,2},
{101,0,2,1,2},
{104,1,0,0,3},
{106,1,0,3,4},
{109,0,3,5,1},
{112,2,1,0,2},
{114,1,0,3,1},
{117,1,1,2,1},
{119,1,4,2,0},
{122,0,1,1,1},
{125,1,0,0,0},
{127,1,2,0,1},
{130,2,1,0,0},
{132,2,0,1,0},
{135,0,1,0,0},
{150,0,0,0,1},
{171,0,1,0,0},
{205,0,0,0,1},
{220,0,0,0,1}}

I guess that some (first) values 
can be found analytically.

Thanks, Zak
