Finished unit 15

Finished unit 15 of tactics module 1. The program finally considers some positions as learned. 60 out of the 342 unique positions i've encountered to be exactly. Personally i wouldn't put too much value into PCT's considerations, and the reason for that is simple... PCT is designed in a way, that if it encounters one and the same position for six times throughout your training, it will consider it as having been learned. But it does not keep track of how many times, out of the six times you've encountered that position, you made the wrong choice... What i am really trying to say, is that you should only value it's considerations when stuff actually feels learned.

Anyway, i hope my posts make sense most of the times, cause what i am trying to explain in English, sits in my mind in Dutch. Now, i know that the Dutch way of saying what i am trying to say is correct. But to translate that to English, and try and make it look the same as it would be in Dutch is pretty hard to do :)

That sounds cool. I was under the impression that you had to get it correct 6 times before it was "learned". Is that true, and if so, can you increase the number of times before it considers it learned?

I have been in contact with PCT support a while back, to ask about PCT's workings. They replied with the following;

Actually, everything with algorithm counting of the Personal Chess
Trainer is alright.
An exercise is considered Learnt after it has been studied at least 6
time through the training process.
I mean, for example, an exercise appear in the Unit 1, after in the
3, Unit 4, Unit 7, Unit 11 and Unit 15. After you see and solve it at
this 6 times, the program will consider it Learnt.
That's the basic concept of our method, to print it into your mind
through this unexpected repetitions.
Coming back to the example, for sure at the Unit 15 you are going to
remember this problem and solve it without difficulty.
So, after it you have printed it into your mind and if you find this
kind of problem one day, in your games, you'll overpass it quickly,
doing the best move.

Any other doubt, please contact us

This was from the actual email i received when contacting them. To my knowledge, it is not required to get it right 6 times before a position is learned. I mean, if you encounter the same position 6 times throughout the training process, and you let the program give you the solving hint, it considers the position also as learned. That is what i am trying to say with that you shouldn't put too much value in the program's considerations, as there might be people who encounter one and the same position 6 times, and still do not see it. But still the program will say that you've learned the position.

And no. You cannot increase/decrease the number of times. 6 times is just a set method of PCT.

What a strange email!

What exactly is it that you find strange about it Blue?

First, the English is funky. Second, instead of admitting that there is something that they might improve in their next version (make it variable how many times you have to see something before it is counted as solved), they confidently say that six times is sufficient, period. Strange.

Well, the reason for the English being funky is easy to explain. PCT is developed by a Brazilian based company and most of it's workers are from the same origin, so...

Yes, I work with a bunch of Brazilians, and that email was very Brazilian in its flavor.
