Update:(seperate post deleted by moderator)
Since we are not in a perfect world, its a gambling.
Doing the risk/reward calculations before entering the ride helps us to not broke.
And finally, the ride goes on till we find a block.
Update:
And we came out freehand.
Let's go to the next ride.
Thanks willi for managing this ride.

Schade, hab gehofft dass es mit den Bestshares so weiter geht wie zuvor.
Wielang haben wir noch mit dem Rental? Mich kannst du für den nächsten Run gerne noch einmal einplanen.
Hab dich aufgeschrieben, kannst deine Coins jeder zeit sendenWielang haben wir noch mit dem Rental? Mich kannst du für den nächsten Run gerne noch einmal einplanen.
Restliche Zeit --> ca. 0d 18h 12m

from my point of view:
- if we mine and stay mining in the future, we will find a block (more blocks)
, it is only a question of time
- if we adjust the hashpower to the diff change, i.e. hire more miners, then we might find a block earlier
- but I would stay with 20 to max 30 PHs, because there are several blocks found with a very small hashrate (13-200THs)
- the Luck is calculated from the number of shares compared to the diff, so if we need as many shares as the diff is high, the Luck would be 100%.
Hope that I am right here, if not please post your feedback or other suggestions.

I agree in points 1,2,3.
I cannot tell if point (4), i.e. luck, is correct or not.

wieder nur ein kleiner Sprung, wo bleibt der ersehnte Sprung über die Diff
Hier eine kleine Statistik über alle unsere Blockparty Runs
Hier eine kleine Statistik über alle unsere Blockparty Runs
Code:
Block 1 found with a luck of --> 14,26%
Block 2 found with a luck of --> 13,93%
Block 3 not found yet, luck at the moment --> 47,36%
Invest in 2021 / 2022 up to Blockparty 11 --> 6,16 BTC
Return in 2021 / 2022 up to Blockparty 11 --> 12,31 BTC
Diff has climbed from 14.363.025.673.660 to 26.690.525.287.406
Willi, Thanks for your inputs.
Dont we need to consider the parameter Hashrate too along with Diff, Luck, etc.

My vote is changing to 30PH/s if we have enough fund to survive atleast 24hrs.
Coins sind raus. Dann mal los! Würde 30 PH/s zwar begrüßen aber laut Voting liegen 20PH/s ja weit vorn.
Und sorry @Unknown01 - weißt ja, wenn ich dabei bin wird garantiert kein Block fallen!
