What's the Best Approach to Track How Fast Clients Respond to LI Invitations?

Hello,

I am kinda new to Zoho CRM and trying to learn new things particularly in reporting/filtering.

I'm trying to figure out how to track in Zoho CRM "how fast our clients connect back via LinkedIn".

BACKGROUND:
  1. We use LinkedIn as our main platform to get connected with our clients.
  2. In Zoho CRM, we have a field called "LI Connect Msg" for our Leads. This is where we place the "message code" that we send to our clients when connecting to them via LinkedIn. (For example: U463, LI470, LI471, etc ...) Looking on this field will tell us what kind of message did we send out to our client.
  3. We also have a field called "LI Connected" (a checkbox field). We're checking this field if we see that the client has responded to our LI 'Connect' invitation.
  4. We can obviously track how many individuals connected back when using a particular message by filtering using the two fields, then compare it with other messages.
    For example:
    1st filter: LI Connect Msg = LI463
    2nd filter: LI Connected = (yes)
  5. My challenge is how to create a report/filter in Zoho to track how fast these individuals connect back based on the type of message we send out. For example: If -- 75% connected back within 3 days; 20% within a week; 5% within 2 weeks, etc ...
Is there a way / what is the best way to do this in Zoho CRM?

I hope I explained that well.
Thank you so much!
