Subform Limitations - flexible amount of phone numbers.

Subform Limitations - flexible amount of phone numbers.

I just read in the Zoho CRM API that the number of entries in subforms are limited to maximum 200 entries for *ALL* records:

A module can have a maximum of 200 subform records with each subform having a maximum of 100 records

I've been told I could use a subform to store a flexible amount of phone numbers to my contacts record using a subform. However, I have 50000 contacts. If only 1% would have 1 additional number in the subform, I'd already be above the limit.

Am I right or do i misunderstand this?

Many thanks
