Using FRAM

I have a project where I need to keep track of three counters and transmit them from time to time.  It has to be power cycle proof so I think I can use the FRAM to store them.  My question is given that I may write to the FRAM 50 - 100 times per day to update the counters I am concerned that this may "wear it out."  Do you know the number of write cycles the FRAM will take before degrading?

The chip used as FRAM is a MB85RS64A, rated for 10^10 read/write operations. Also with 100 write per day it take some time to wear out...

Why not use the I2C eeprom instead?
