  There'd be no solid correct answer to your question. The flushes can vary no matter which sequence order you are talking about.

I had a second calver drop 21 eggs and 18 ended up viable. They told me she was in good condition and I had a guy do the rounds of injections that had done it previously so we could maximize the flush. For little guy, its kinda costly. But I was told lot of variables with it- condition of cow,etc . My guy flushed his cow who was about 6-7 yo old lady and got 28 viable eggs and they have had a great conception rate as well. So well, he said his herd is so small he has to put one in just about every cow to get them used up before they go out of style.  :)so he seems to have a knack for setting one up.

I think that is a cow to cow matter.
I flushed a 15 years old lady, 10 calves, and she got me 9 and 12 embryos on a sequence flush. She was first flush ate 15 years with a 65 days between both flushes, tomorrow will to be inseminate for her 3rd flush.
Also got a 2 years heifer that gave me 7 and 8 embryos.
Some cows with 3 and 5 calves makes me none embryo too.
Think that a good weather (no hot and warm), a good condition score of 3 to 4 and hormones of good quality made on correct time, with a quality semen, are 90% flush success.
Tomorrow will starts more 10 donors cows and heifers, a late summer season with no more hottest days. A good semen will to be used and cows are 4 to 5 SC (1 to 5 scale).
Hope to get success!

I have done a few hundred flushes in the past 10-12 years and I have not been able to see any pattern as to when is the best time to flush. I have had the best flush on the first flush and also have had the best flush on the 10th flush. The last flush we did was a few days ago, on a donor that has been flushed 3 times at 2 month intervals between flushes. The first flush produced 19 grade one embryos and no unfertilized or degenerates. The second flush produced 4 grade 1 and 2 unfertilized and the third flush resulted in 2 grade 1 embryos and O unfertilized. The same sire and the same cane of semen was used in all three.  Another older donor was flushed 12 times over 2 years and was becoming very arthritic and the ET center suggested we may have to ship her. They were afraid she would eventually lie down and not be able to get back up. Her embryo production had been falling off and we were only getting 2 or 3 good embryos per flush. We made the decision to send her to town before she had to be put down. The following day, the vet at the ET center phoned me and said he had been reading about a new drug that showed promise with some cows that had this type of arthritic condition and he asked me if I would permit him to try it on her. I agreed and said that seeing she was close to the time she would be flushed again, that maybe we might as well try her one more time. This flush resulted in 17 grade 1 embryos, the most she had ever produced in her flush history. That was almost 3 years ago now. This was our Prairie Lane Sparkle cow and she is still here at nearly 16 years of age and is still being flushed. She looks better now than she did when she was 9 or 10 and has had no issues with arthritis since she was treated. She walks a little slower now, but I also walk slower than I did when I was 20. At 15.5 years, she is still one of the fattest cows in our herd and was wintered on only hay. I am wondering if I was to threaten my donors with a trip to see the " Golden Arches" if that may work to get them producing more embryos.
The best embryo producer we have ever had produced 328 embryos from 12 flushes also done at 2 month intervals. She averaged 28 embryos per flush and the last flush we did was the smallest one and only produced 8 grade 1 embryos. She was brought home to rest for awhile and was bred 5 days after her last flush and produced twin heifers the next spring. She is also still here and will calve any day again.
If I could ever figure out a pattern as to which flush will be the best, I could probably make a small fortune, but it is basically a crap shoot every time you flush.

Same kinda deal here, we used a bull on two cows, 7 eggs from cow X and 11 eggs from cow Y on their flushes...then cow X did 8 and 10 with two different bulls and cow Y did 5 with the same bul that did 8 on X and is set up right now...these two cows are 12 and 13 year old first timers.
