In general, there seems to be a limit to which new inquiries can affect - I think 10%. Which is 10% of 600 (900 minus 300) = 60. If you ACE timely payments, utilization, credit age and mix, you can get 840 (900 minus 60) even if you apply for a few loans every day.
I'll pull my report early June and share. Got a PNB Platinum RuPay Mar-Apr, IDFC - got pre-approved Classic (opted Millenia) and those [insert insult] refused WoW - both in Apr, then an ICICI Platinum and Kotak Urbane this very week!
