numbers, statistics, excel sheets, gosh how I hate them -)
I made a screenshot with my results from last tournament, is this the correct way, how to calculate your rating?

The standard deviation on a 10 game performance rating should be over 100.
The quick calculator is going to be pretty accurate by comparison with this SD (examples show it the error introduced is very much smaller)

So I plugged my games from our four events so far into a performance rating calculator: http://www.kosteniuk.com/EloCalc/elo.php
The results vary rather wildly!
May 2017 Test-run event: (2/7) 1184
June 2017 UTT: (4.5/8) 1763
June 2017 Sat: (5/8) 1650 (would have been 1600 if the final game had been lost, and I was up against a stronger opponent, but he had to leave so we agreed an early draw)
July 2017 UTT: (3/8) 1372
July 2017 Sat: (2.5/7) 1424 (I also had a bye)
August 2017 UTT: (3/9) 1288
August 2017 Sat: (3.5/9) 1595
Interestingly, I had a higher performance rating in the June UTT event than the following Saturday event, despite scoring slightly fewer points. That's because I started with wins in the UTT event, and thus faced mostly strong opponents all the way through, whereas in the Saturday event I started with two losses and then recovered, so more of my games were against weaker opposition.
