I really don't like entering columns as letters for the battleships answer keys. It could be digits, it's simpler to read, and faster to type on a numpad.
Same for polyominoes, it could be the size of the colored parts, it's faster to type than letters.

Thanks for your viewpoint and we are concerned that you found the answer keys horrible while most other participants were ok.

For Polyominoes, your suggested answer key is an altogether different kind of answer key and does not clearly tell if the solver placed the correct polyomino. So the letters do serve a purpose here. Last year, we had asked names of the first three shapes from a direction, again letters only.

For Battleships, letters are already provided for easy reference above the grid. So it should not be that difficult. The numbers are avoided for a reason again. Numbers can possibly cause confusion with battleship outside clues which are also numbers.

Yes, we do consider things like "simpler to read" and "easier to type" but that is not the only consideration.

Good test, although harder than I expected! I got everything but the last two Kropkis. The quality was very high, in my view. Thanks!!

Phew. Finished this test with a minute to spare.
I was really slow with the Latin Squares.
Thankfully, I made up for it with the Object Placement portion.

Number Placement should perhaps include other genres as well (maybe Products, Summon, heck, even Nansuke?) - 3/4 types being Latin Squares was maybe a bit... much.
I noticed a wild imbalance with points/minute solve - but this is often common with the placement genre since you could quickly intuit to a solution.
For example, I took only 90 seconds to solve 8 points worth of Akari, whereas I'd take 10 minutes+ to solve 8 points worth of Kropki.
The presentation of Weighted Battleships (I think that was the original name) could've had the digits written on the ships (which is usually made lighter grey) to make it easier to visualize.

Loved the test. You could see the intended logic path behind most of these puzzles. The 14-Battleships deserves a special mention.
Thanks!

A question: if every test is going to be extended by 24 hours, why not just start each test with the extra day already included and save yourself the hassle?

Yes. It is a valid point and has been discussed internally too.

There is a reason we are not doing it. If we directly do it till Wednesday then people may ask for extension till Thursday and we want to avoid that.

Thanks to LMI for giving an opportunity to Pranav and me to author PR2. Thanks to Rakesh for guiding, test solving and overseeing many other things in the background. Congrats to the podium finishers. There were 21 solvers (across 8 countries) who finished all puzzles in time. The test got inclined towards the hard side and general feedback reflects the same. We take constructive feedback of choosing variety in puzzle types. It is a learning curve for us and we see an opportunity in improving the balance of the test for wide spectrum of puzzle solvers. Special mention of Pranav as he came up with an amazing set of puzzles. It never looked like he was authoring for the first time.

Congratulations to Endo Ken, Kota Morinishi and Hideaki Jo for completing the all Japanese Podium, and congratulations to Prasanna, Rohan and Ashish for finishing in the top 3 among Indians.
It was a test on the harder side going by the feedback. The lack of puzzle type variety is a quite valid criticism, and we shall keep it in mind for future rounds.
It was a nice experience to author PR (for the first time). Thank you to Harmeet and Rakesh for helping me with puzzle ideas, test solving and their general insights!
It was fantastic to see the solve path and general smoothness of Harmeet's creations as I test solved, and its something i will try to incorporate into my creations as well!
Looking forward to the next round!
