yep agree with Sarenco. I had calculated similar, the worry would be the limited buffer.
That said continuing to work thru to 67 in P./t and freelance roles, if secure incomes, this does add a lot of stability. Should there be an unexpected event/market crash etc, perhaps you could cut your cloth - look at your minimum required spend. e.g. Reducing to €30k Exp where needed could be all the flexibility that's needed to sustain through tough periods.
You didn't mention what you do now, I am assuming in a PAYE that you would be leaving to do freelance. Given we are still in lockdown, perhaps setting a target now for 1-2 years, will allow you to establish the freelance stuff ready for when things settle down, continue to build the pension pot and give you a countdown as motivation.
