When I started I had a score of 793 Fico EQ - 6 new accounts (incl. 9 inq Cap1 triple pull, Chase 2 x double pull and 6 new accounts reporting) my score dropped to 738. AAofA from 18yrs down to like 5 years 
After about 4 months it came up to 773 again and November my first card hit the one year mark and I almost made it back to last year's level ..score is 785 now. Two more months to go and then I will see if I made up all my points lost. ....from now on I will not do app sprees but rather space my apps at least 3 months apart as there are only a few cards left that I might be interested in.
