Does rating increases in bulks or is it a steady increase?

I have been taking lessons from a coach since two months and I also played my first OTB tournament two months ago. Since then I have played around ten tournaments with an average of one or two tournament every weekend.
Even though I have learnt a lot from every single tournament by analyzing my games with the coach, and I myself know I am more knowledgable and experienced now then when I played my first tournament my rating has just fluctuated between 1000 and 900 throughout.
My question is does the rating increases in jumps in general or is it like a steady increase where you increase rating points gradually playing every tournament? If its a steady increase, then I am sure I am not doing something right.
If I am 900 something after two months, is it a realistic goal to aim for 1500-1600 in the next 10 months, with coaching and playing 1-2 tournament per week?

Thank you for your reply. However, you didn't answer my initial question of rating increments either being in bulk or of steady increases?  I see that you are a 1600 rated player yourself. How was your improvement?

So If I am 900 since two months, I might see a sudden jump of a 100 or 200 points if I keep playing
