Rolling Average vs Gradient Descent with Softmax & Cross Entropy

If each Guess Factor bin is considered an output unit before Softmax (logit), and loss is Cross Entropy, then the gradient of each logit is then:

q_i - 1, if bin is hit

q_i, otherwise

If gradient is not applied on logits as normal, but instead applied on q_i itself, then:

q_i := q_i - eta * (q_i - 1) = (1 - eta) * q_i + eta * 1, if bin i hit

q_i := q_i - eta * q_i = (1 - eta) * q_i + eta * 0, otherwise

Which is essentially rolling average, where eta (learning rate) equals to the alpha (decay rate) in exponential moving average.

Anyway this analog isn't how rolling average works, as logit doesn't equal to q_i at all. But what if we replace rolling average with gradient descent? I suppose it could learn even faster, as the outputs farther from real value get higher decay rate...
