mfu_shortstorie one of mine has been rec'ed by

k1p2psso It's a story that features Illya, A Russian In Survival School on MfU Archive.
In it I have IK at Survival School at the age of 22, something that seemed reasonable to me at the time I wrote this, which was fairly early on in my short span of writing years.
Now that I look at that, it doesn't seem correct in terms of a timeline. I know I've probably referenced it differently in later stories, but I'm curious to know how you, readers and writers, have that event in your own timelines for the Russian.
Inconsistencies are the bane of writers in this genre, hopping from one year to another. Unless you're meticulous in how you place your details (I'm thinking of

mrua7 in that respect), then you're liable to be like me and run into some surprises when going back to earlier works.
I've gotten better, but how are some of the rest of you doing?
I suppose we're in good company, the series writers were notorious for throwing things in that made no sense whatsoever. Are we influenced by that, or just not keeping track of our own work?
Tell me. Speak up!
