Number of Cards Reporting

Question

I noted this as part of another thread earlier, but decided to put the update here.I have 16 cards reporting balances as of June and July. Through mix ups in keeping amounts on all the accounts, I ended up with a series of 3 of the cards reporting zeros in various combinations during late June and to late July when I was able to get them back to balances. 16 cards reporting is 100% of open and reporting credit cards. Two closed cards and Diners are not included in the TU numbers, AFAIK. It appears the significant change factor for the TU score during this time was the number of cards reporting. The image below is read from right to left, increasing calendar days from right to left. I have removed columns where there was no score change, balances are within a $2k range the entire time, and utilization percentage is nearly the same, no CLI changes or new accounts reporting. June was a month where utilization dropping began to be realized, so some of the initial score increase is left over from that. First row is balance being reported. Since TU is a jumble, I have to prove out which cards are making up that balance, so row 3, Diff, is the verification that I've got all the individual cards accounted for on that day. The With Balance is the number, out of 16, which are reporting any non-zero balance. Add Zero Balance count on the next row, is always 16 total in this sequence. The TU FiCO row is the score from the myFICO alert on that day. In all the gaps in days, there are no other TU score changes. On 6/25 as the first card goes to zero, no score change.On 6/28 after two cards have gone to zero, there's a 6 point bump.On 6/30, as 3 cards are now zero, there's another 9 point bump. This is likely somewhat influenced by the remainder of the utilization improvements in June. On 7/2 as one card comes back to report, a 2 point drop.On 7/24 as the other two cards come back to report, then a further 6 point drop.  

Answer 1

I'm going to gather some data. I will go from 4 of 6 cards reporting to 3 of 6. I have been moving my bills over to my PRG from my BCE and I believe I just got the last few holdouts moved. I will pay down anything, if anything, that still goes on the BCE to ensure it doesn't report a balance.
My utilization is under 4% and will stay that way as my spending on my PRG doesn't count. My non Amex transactions go on my BoA travel and I typically have a little on my Amazon store card.
Not optimizing to app anything so I will let the PRG, BoA, and Amazon cards report, but the BCE should go to zero for the first time.
Score currently 726, let's see what 1 less card reporting but with the same general level of utilization results in.
