Default TF'ers: what's your longest streak?

I'm just curious: what's the highest number of factors you've found in a row?

My personal record is three. What's even more impressive is that I found them on my 1.7 Ghz Pentium M laptop.

This was before I merged my PrimeNet IDs into my current one, which explains the strange username and computer name.

Anyone have a longer "combo"?

In May, I had a (double) blip that changed the scale of my plot forever.
I believe that that was two threes in a row.

I don't usually get factors "in a row" per se, but I've had several (read ~5) exponents that I've found 2 factors for in the same bit. (65->66)

Does it count when I have ~2500 results and the factors pop to the top?

Is a negative streak interesting too?
During my entire GIMPS history I have done 140 TF runs, all between 64-65 and 68-69 bits. Not a single one turned up a factor.

I've had a least a couple days with 9 factors. I've also had many days with no factors and I think 1 two-day streak of no factors.

It heavily depends of the ranges and bit deepness you do. When I helped Uncwilly to clear the 100-digits (332M and 333M) range to 69/70 bits I found 140 factors in 10 days, and many other later when I extended the 332M to 70/71 bits. That makes average 14 factors per day, but I would consider a bigger success when running 60M assignments to 72-73 bits and find a factor every few days.

Edit: if you need lots of factors, pick a high range with low bit limit, say like 3xxM to 70 bits, and put your GPU on it for a week. You still can find a factor every few hours.

I approve of this post.
