Vodaphone Fibre, inflation increase doesn't seem right?

I signed up at £24pm for 2 years.

Contract says:
"Future charges: Each April your monthly plan charge will increase by the consumer prices index (CPI) rate published by
the Office for National Statistics in January plus an additional 3.9%."

ONS says:

"CPI inflation was 10.1% in January 2023"

The latest bill shows the new monthly rate to be: £27.46 which is an increase of: 14.42%

Shouldn't new monthly rate be: £27.36@14%?

----

Note: Before you post to say '..its only 10p', it adds up to £2.40 over the contract period and an extra £43m if applied to Vodaphone's customer base.

Close. The inflation figure used is that for December 2022, published by the ONS in January.

If your plan started from 2 February 2021:
Your agreement provides for your monthly cost to go up by 14.4%. This reflects the UK Consumer Price Index (CPI) at 10.5% (as published on 18 January 2023, plus an additional 3.9% to cover the increasing costs of operating our network - as set out in your agreement with us.
