If you pull your CRs from annual credit report for all 3, which are free to pull weekly, (or through TU for just your free TU CR which is the same as the ones you get from annual credit report), the you can monitor for when Cap One SPs your reports.
For me, they have SP'd my reports monthly or even every 3-4 months at times. For my SO, they have also SP'd his reports as frequently as daily!
Just keep an eye out for when you see the next SP and then try for your CLI then.
They will use the score from the last HP, even if it has been 4 months and you have doubled your score. That is just how Cap One does it. Lots of banks do it that way.
Giod luck and hopefully they SP soon!
